TCL C715 HDMI ARC output issue (Low volume) after OTA update - Philips, Sony, TCL Android TV

My TCL 55C715 received just received an OTA update just yesterday. After reboot, I have an issue with audio output through HDMI ARC. If I select PCM or Passthrough in the audio menu the volume output is too low even if the soundbar (Sony HT-RT3) is at max volume., only, if I select Auto in TV audio menu has a normal volume but just stereo. If I use Netflix in Auto the sound is 5.1 but in YouTube, the 5.1 test in Auto the rear speakers don't work

I hace the same problem, with an onkyo receiver, please upload the old firmware

What has been your previous version ?

My Software version is LF1V634 and my TV Model is 65P8S

Has anyone found a fix for this issue?

You should try to install the latest official version (V645). Maybe the problem is fixed by now.

Hello i have TCL 65C715 OS version V5.2.0 software version V8-R851T02-LF1V634.018640

hello,
any news how to solve this issue?
my TCL 55EP640 was working fine with ARC pass through and a onkyo tn-nr656. out of nothing it stopped working, only outputting from setting auto and in DD stereo. first i thought it was a issue from the receiver, so i tried to use the TOSLINK output and the issue is exactly the same. When the tv is on pass through or pcm, the receiver says PCM 2.0 but no sound, when the tv output is on auto the receiver detects DD but it says unknown on the format, it can't detect it is 2.0.
i was reading that the tv might be outputting pcm way too low, but i've cranked the volume from the receiver and nothing came out from the speakers...

Well and update, it turns out that the TV was outputting pcm sound, but is really really low. I have to crank the avr volume to max te hear something.
Is there a way to increase the output signal?
I've tried the menus and couldn't find nothing. Any ideas?

Hello again!
I've found a solution!
It appears that the pcm output was way too low so I accessed the service menu and changed the audio settings as the pics.
In my TV (55EP640) to access the service menu:
Settings->picture->advanced->color and contrast->put the cursor over contrast->press 1950 and the menu will appear.
Hope this helps

[Q] DTS/DD passthrough

Has anyone got this working? This is really my main complaint with this device. Stereo is like so 1980s!
XBMC have DD/DTS passthrough.
I'm using xbmc. Is there a certain test version you use to get it to work?
Sent from my Nexus 4 using Tapatalk 2
I use the one from july 14th. The passthrough is enabled in settings when you select HDMI as output.
Settings - > System - > Audio - > HDMI as output and 5.1 (or more) as number of speakers.
And it actually works? It shows up on mine too, but nothing comes out. I don't recall which version I'm using. I'll check it out later and report back. Thanks.

But I had it working also with other stagefright versions.

I tried the linked version as well as the latest nightly and test versions. None have worked with DTS for me. I even tried on receivers from 2 different brands. They both do the exact same thing and release this loud noise instead of any sound. Does your receiver actually say DTS on it when playing the files?
Someone got it working on their Onkyo. I've been watching stuff with DTS and DD 5.1 this way on my TX-SR606 for several weeks on XBMC (libstagefright nightly builds). I checked my speakers, it does work.
"Go into Settings > Hardware Setup > HDMI >
Turn Off HDMI Control RIHD
This will now show an option called Audio TV Out (This passes audio to the TV when you don't want to use your speakers)
Turn this on and Voila you now have DD/DTS on every video you play"
This is from the "DTS audio via XBMC possible?" thread on Ouyaforum_dot_com (I can't post links yet).
If that doesn't work on your receiver, there's another (annoying) way: Start playing movie file, turn off receiver, wait a couple of seconds, turn it back on. The DTS or DD audio should light up. Sometimes it takes a couple of tries for it to work. If you pause or stop and replay, you have to do that same power cycling again.

Ok just got mine to work. I have a Denon and changing my Audio out to TV only stopped any audio for me. What I did was have to go into input setting and change the decode from Auto to to DTS (which stopped the audio) then back to auto and it works for DD and DTS. Turning my receiver off and on and changing channels didn't work either for me.
I tried fast forwarding and once in a while it would kick back to the loud sound and I would have to change it back. Tomorrow I'll watch a whole movie without fast forwarding it and see if it does it randomly or just with occasional FF.
Thanks for the help.
Actually, leaving it on DTS mode works too if you're watching a DTS movie. I have no DD only option, so going back to auto seems to work best for me.
I'm just happy there's hope for this to work automatically in the future. Then I will finally be done with my HTPC! Yay!
Hello guys,
I have a big issue with HDMI passthrough on XBMC on my Ouya. May be (I hope) you can help me :fingers-crossed:
My install is a little bit strange : I have an old audio receiver with no HDMI connector So, I connect my HDMI devices on my TV (Sony KDL-V5500) and use optical output from my TV to my Audio receiver (passthrough) that will decode audio stream.
With all my devices (XBOX, Raspberry Pi and XBMC, Internet provider TV box), it works very well... My TV has sound, and if I want best quality, it is possible to start receiver (and decrease sound on TV).
With my Ouya, sound is not sound but noise... With DD or DTS sound it is the same thing. I tried to stop TV and restart it to reset audio hardware but no way.
An idea ? Is my TV not compliant with HDMI passthrough from my Ouya ?
Thank you for your help...
Guys, playing movies on my ouya was the main reason for me to get it.
I've managed to solve dts issue, but only partly.
Follow these steps:
1. Hookup ouya to amplituner
2. Hookup amplituner to tv
3. Turn everything on, and set hdmi source on amplituner to ouya
4. Make sure hdmi output is set in xbmc settings for sound on ouya and you selected 5.1 speaker config or better
5. Start playing dts movie in xbmc ( it must not be dts-ma hd)
6. You get static in your speakers
7. Turn of amplituner so it switches to pass through mode
8. Wait couple seconds
9. Power on amplituner, so it recreates hdmi handshake with ouya
10. Profit, you have valid hdmi session and dts plays nice
There are some drawbacks.
1. If you pause a movie you have to redo steps 7,8 and 9
2. It doesn't work for dts-ma hd sound
Can someone tell me if dts-ma hd doesn't work because android kernel doesn't support it or for some other reason ?
I googled it A LOT, and found only bits and pieces of information, some say it's android kernel limitation and some say it depends on app I'm using. Anyway I'd like to enjoy all types of sound in my movies.

[Q] Surround Sound Support in Kodi

I am using Kodi on my Fire TV and noticed that the movies are only playing in stereo mode. The Dolby settings on the Fire TV itself are set to automatic and trailers play in surround sound. Are there settings in Kodi that need to be modified? Any help is appreciated!

Go to the audio output settings in Kodi, and make sure you are on the expert level. Put the number of channels to 2.0, passthrough enabled, and select all the audio formats at the bottom.
Yes I'm struggling getting surround sound as well, have lived with it up until now as usually everything I'm watching says 2.0 stereo, but last night actually found something that said 5.1 and I wasn't getting any sound from that! lol
Have tried different settings (as above) but still no sound through my amp, have only just really started looking into it but nothing worked in all the different guides I tried.
Will hopefully get this sorted soon, there are quite a few settings in the expert mode so will hopefully get round to trying them all, it's just having to go back and forth after changing the set up that's the pain lol

I have an HDMI connection, when playing a 5.1 video I can see the front left/right speaker icons stuttering on my amp (usually it would show all 5 speakers) and no sound comes through. I suppose it could be the stream but think it's probably my settings...
Is the amp supposed to convert even when playing a 2.0 stream or does it have to be a 5.1? I have always assumed it has to start as 5.1 which is why I've left it until now

Some amps will convert a 2.0 audio stream into a fake 5.1 stream, but it's an actual setting on the amp. Do you have DD audio set to On in the settings for the AFTV? What brand is the amp?

Yes I've set it to DD Plus via HDMI and have now pretty much tried all the settings in the audio options including 2.0, 5.1 and also (my setup) 7.1 but none seem to work, have also tried changing the Output config, Stereo upmix, Resample quality, Keep audio device alive but nothing is happening, still getting no sound when it displays 5.1 DD on the stream, even tried another episode and the same thing.
My amp is a Sony STR-DA3600ES which is DTS capable but like I say the speaker icons flicker when playing the stream so there's definitely something not quite right
I have never had problems with anything else so think I may have to just give up on this Kodi problem

Here are my exact settings, and 5.1 audio plays perfect. If these settings don't work for you, then it might be that the AFTV doesn't play well with your amp when connected with HDMI. I bought a Denon amp a few weeks ago, and no matter what the settings were, I couldn't get 5.1 audio to work. I returned the Denon, and bought a Yamaha, and 5.1 audio plays perfectly. Another thing you can try, is run an optical cable from the AFTV to the Sony, and see if that works. Make sure you go into the AFTV settings and change the audio output from HDMI, to optical. You may also want to try a new HDMI cable.

Cheers Lennie, I thought about changing the HDMI cable so will definitely try that when I get home, if not will try optical as I didn't even think of that lol
Have tried your settings already (although didn't have the volume on downmix option) with no luck so the cable changes are the only thing left, will let you know how I get on... :good:
I managed to have a look at this last night (after searching various forums) and thought I would try XBMC to see if anything broke in Kodi 14.1, so installed the last Gotham built SPMC (13.4.0) but that had exactly the same results.
Pulled out all my equipment to change the HDMI cable over but that made no difference either, so plugged in an optical cable, changed the audio input on my amp and changed the AFTV to DD over optical and had 5.1 sound straight away :good:
So looks like there's something strange with Kodi/XBMC when trying to get 5.1 surround using HDMI on some amps...

Glad you got it sorted out. Like I said, I bought a new Pioneer a few weeks ago, and couldn't get the audio to work using HDMI. I returned it and bought a Yamaha, and it works perfectly. The only reason I figured it out, was when the audio wasn't working, I took the AFTV and hooked it up to my other home theater setup, and it worked fine with my Denon receiver. The audio was making a really high pitched static sound when using the Pioneer. My Xfinity box's audio worked fine with the Pioneer, so I know it was the AFTV, not the Pioneer, that was the issue.

Know this is a old thread but hopefully you will reply. Using Kodt why do we have to select 2.0 to get 5.1 surround sound or am I not understanding what you are saying?

That's because Passthrough has been enabled, which means your receiver is doing the audio decoding.
Interesting. If I remember correctly I did not have to do that with SPMC Gotham 13.2, strange.
I know this is not the right spot but maybe someone could help me. I just got my shield console and it is sending multi channel audio to my receiver. I DO NOT want multi channel audio i want 2.0 audio. Does anyone know a way to NOT send multi channel audio?
Very helpful thread thanks!
Just a query though...
If I have 'Number of channels' set to 2.0 and have 'Stereo Upmix' on the reciever seems louder and high quality but with vocals coming out of all speakers which to me it should be centre speaker only. But if I have 'Stereo Upmix' off the centre channel is vocal only which to me is perfect but the quality is lower.
Is it just how it is or am I doing something wrong?

FYI, if you want to keep DTS Passthrough, don't upgrade KODI past 16.1 Jarvis. DTS passthrough is gone in Krypton on AFTV because that "Android" standards require API 23 (Marshmallow/Android 6.0) to "officially" support DTS and AFTV is still on API 22 (FireOS based on Android 5 Lollipop). I don' t see Amazon updating to a Marshmallow based image for FireOS anytime soon. It is a sad day.
Also if you want dts passthrough you can't enable "sync playback to display" otherwise it's going to passthrough as Dolby digital.

Low Volume on Fire TV 4K box

Hi All,
I have a AFTV 4K box which has had an update yesterday to 5.0.2.2 to resolve issue with Dolby Digital, however, the problem I'm having seems to not have been resolved, even after factory resetting it after the update. There seems to be an issue with the volume that's outputted from the box in that it's very low. Even with Dolby Digital Plus set to off the volume is low. I have a Samsung smart TV and have the Fire TV connected via HDMI. I do not have any sound system or sound bar connected; just the standard TV speakers. The volume level range when I'm watching cable TV through Virgin Media, or a DVD through my Sony Blu-ray player is set between 8-12, however, with the Fire TV I have to crank it up to 35+ to get the same volume level. I have tried different HDMI cables and different HDMI ports on the TV but the issue still remains. I have this problem across different apps such as Kodi, BBC iPlayer etc. I've hard wired the box directly to my router and have good internet speed (100Mb).
Is anyone else from here having this issue, and do you have any suggestions? The volume issue is really annoying.
Thanks.
Is no one else on this form experiencing this issue? I see there has been a lot of views but no responses. I've contacted Amazon and they've passed on the issue to the engineering team.
For anyone checking this thread, I just had a call from Amazon support who confirmed that this is a known issue and is affecting a number of people. A future software update should resolve this, however, he's still waiting for the engineering team to provide him with an ETA of when this software will be released.
I am having the same issue. Thanks for the update
For those that may be following this thread I ithought I'd let you know that software update 5.0.3 has resolved the low volume issue for me. My box received the update earlier today.

TCL P715 digital audio out

External soundbar connected via digital audio out. Set to PCM mode. Sound still comes from TV speaker. Tried setting Auto and Pass Through. I can turn TV to mute but then mute icon appears. When using TV volume up or down, TV speaker starts playing again. I want only the sound bar to sound, no sound from TV speaker, and volume control via TV remote. How?

You can't as thing stand now. What I do to get around this issue it to keep the tv volume at 1.
This issue comes and goes (might depend on the order which devices are powered on).
New issue - with latest OS update there is a significant audio delay on some inputs.

ARC stops working and tv switches back to speakers randomly

Hi!
I have a TCL BeyondTV2 (C715) and a Harman Kardon AVR 171s, that has HDMI ARC capability. My brother who owned the system before used it without problem with a Sony Bravia TV (I don't know the exact model) through HDMI ARC. (I think he only had an issue that the AVR could not turn on with CEC only off, but I think he just misconfigured it)
Now I have the AVR and tried to use it with my TCL C715 through ARC, but with no luck. I have all CEC and everything set up, and it is works... for about 10 minutes, when the TV switches back to speakers, and TV remote stops to relay volume up and down controls to AVR. If I switch the input on the AVR from HDMI to something else and back, sometimes it comes back for another 5-10 minutes.
If I use the AVR with S/PDIF the audio is fine, but obviously I cannot control it with my TV remote so, I have to use 2 remotes and separately switch on everything. It is annoying
I recently updated the TV's system to V8-R851T02-LF1V715.000032, but it did not fixed the issue.
I think i have the latest update on the AVR.
Did someone encountered this problem? Does anybody have ideas how I could debug this? I did not find any related posts on the forum, but maybe I missed one. I have ADB set up, so if there is a way to get logs I would be happy to (I did not see anything with logcat, but maybe I used it incorrectly)
Any ideas appreciated!
