A/V Receiver is splitting signal into HDMI video part and 5.1 audio part, but i can get only 2 audio channel. I am using this test files https://www2.iis.fraunhofer.de/AAC/multichannel.html. Do you have any idea where is the problem ?
My scenario is "LG LG3" -> Slimport -> HDMI -> "A/V Receiver" -> 1) "HDMI output" -> LCD
-> 2) "5.1 channel audio"
Slimport is very picky about 5.1 audio. That test file doesn't work on my Nexus 7 (only get 2 channel audio), but on my G3 it seems to be working fine:

I haven't changed any settings on the G3, just using the standard video player
Ok, so, it is obvious that LG G3 slimport is capable of playing 5.1 audio. The real question is how to force LG G3 to send 5.1 channel audio into slimport ? Unfortunately i have no other settings on receiver than change mode stereo, 5.1, pass pass throught.
I think that LG G3 simply doesn't know that it should send 6 or 8 audio channels. May be this information should come from slimport and receiver but it doesn't.
I have this "cheap chinesse" receiver http://www.aliexpress.com/snapshot/6156575582.html. I will appreciate any suggestions.

The problem is not with the G3. As I posted above, I played the exact same file as you on my G3 and got 5.1 output, without 'forcing' or changing any settings on the phone. It automatically sent 6 channels
I think the problem is with your receiver.
Can you try playing the test file using VLC For Android? VLC will transcode the AAC audio to multichannel PCM which the receiver should be able to support.
Also try this test file which has AC3 rather than AAC audio:
http://www.tfm.ro/win32-projects/test-avi-ac3/
I have tried VLC with "test-avi-ac3" but without success. The strange is that all 5.1 channels are comming from FL and FR output, etw. CENTER is comming equally from FL and FR outputs, but no sound from CENTER output, RL is comming from FL output, but no sound from RL output.

So what are you doing?

did I provide a link? No.
before I posted this did you know that you could have android (gingerbread at that) in your car? doubt it. I didn't
search for them on ebay or the web address hard-coded into picture. or google, i dont care, as I will not post links to avoid being accused of trying to sell these. although they are sold out of UK and i am in canada. there are still many complainers on this site.
I want one just to do a system dump on it!
get a DVD app, TV app, radio app with RDS, I pod control?? these functions must be apps....
nice
Hi, I'm facing a problem with my shiny new FireTV stick, preventing it to be used as intended:
I've been using a chromecast stick to listen to online radio streams without problems. That chromecast was connected to a HDMI-audio extractor, comparable to this one: http://www.amazon.com/dp/B013WOLL44/
The audio extractor is connected to the tv (video + audio) and to a stereo amplifier (audio only). That way I can listen to audio streams on my stereo, with the TV in stand-by mode.
When I got myself a FireTV stick about a week ago, I replaced my old chromecast with it. So now the FTVS is connected to the HDMI-audio extractor.
But the FTVS enters sleep mode as soon as I switch the tv into stand-by mode (using the tv remote). So it seems to be impossible to listen to radio streams without the tv switched on.
Is there anything I can do to keep the FTVS running with TV in stand-by? (I even could solder some custom HDMI cable if needed.)
Solution: See post #3!
@spacetaxi
try to install http://forum.xda-developers.com/fire-tv/themes-apps/app-root-home-launcher-replacement-app-t3118135
and set looong Sleep timeout in FireStarter settings
maybe this help
Problem solved!
@Kramar111 Thanks for your suggestion, but that does not work.
During the last days I did further investigations and came to the following conclusion: It is a hardware feature of the FTV stick to go into sleep mode as soon as the tv is switched to stand-by. Of course that does make a lot of sense if one is using the stick for video streaming. But it does make less sense if one wants to use it for audio streaming...
I've been searching for a method to "hack" the HDMI connection, so the FTV stick does no longer recognize when the TV is switched to stand-by... and I've found a solution!
There is a looong thread on the Microsoft Technet forum regarding a somewhat similar problem with some pc video cards: https://social.technet.microsoft.co...onitor-off-detection-how?forum=w7itprogeneral
I've made two screenshots from that page, so we are able to keep the crucial bits of information, even if that thread may be no longer available someday in the future. This is the problem description from the Technet thread:

Hi,
This is my experience with N5X while streaming music through bluetooth to my new Car (Ford Figo 2015 -India).
Play quality - Good so far
Connection Establishment - Good so far
Upload Contacts to Headunit - 100% works
Display song track info - Doesn't work
I have seen devices like LG G2 (5.0 android), Iphones (4,5s,6), Samsung Galaxy Young(cheapest samsung running Jelly bean) connect and stream music info while playing music.
However my older Nexus 4 and my new nexus 5x seems to be hitting roadblock.
Please correct me if i am wrong, but below are my points that could be the root cause of this issue
1. MP3 Players(AVRCP support)
I have tried almost all renowned Music players from Playstore. Tried all bluetooth assistance apps along with them still no luck.
2. Bluetooth Stack
N5x is not listed : https://support.google.com/nexus/answer/6048862?hl=en
AVRCP version is not up to date ?
https://productforums.google.com/forum/#!msg/nexus/_t1ufKwSqU8/76g7UPtwAQAJ
3. Bluedroid(previously BlueZ)
Bluedroid is still in its infancy and bluetooth stack not being upgraded, hence?
Please share your experience with N5X on Song track Info, maybe we could collate all information in this thread.
2016 Volkswagen Jetta with Nexus 5x here, track info displays over bluetooth when playing music files, haven't tested streaming audio or video. No special add-on apps or settings for bluetooth, using Shuttle+ as a music player.

No, that's all I've got.
It wont let me change these settings, regardless of if im connected to a bluetooth device or not. Do i need to have other settings enabled/disabled before i can change the audio settings under the developer options menu?
I have the U.S model with the Qualcomm snapdragon chipset, running android 12 and One UI 4.1, in case that's worth noting.
Im not sure if these will be of any use but just for reference heres 2 screenshots of the menus im unable to interact with.
All other bluetooth settings between "HD audio" and "Bluetooth Audio Codec LDAC:"
I'm unable to change, even though i can open the menus and none of the options appear to be grayed-out.
Sorry if this has been answered elsewhere. Im fairly new here and android 12 as well (most recent android version ive used in recent years is android 8.0 oreo). still learning my way around.
thanks in advance for any help, answers, etc.

tldr: I’m no help, but I can confirm some parts.
I’ve got a pair of Sony WF-1000XM3. As long as the headphones are connected, I can turn on and off the HD audio setting and switch between SBC and AAC (they don’t support better standards).
My old Bluetooth speaker and a Jabra Evolve 65 don't activate this settings, so it depends on the Bluetooth version and supported audio formats?

Yes I can confirm that, same here.
It's as simple as connecting a headset capable of this codecs/options.
I think generally the best option would be selected automatically.

You can only initiate the changes for HD codecs when the bluetooth device is connected. Example, With Sony linkbuds S, I can select LDAC Or AptX. Once configured, the codec activates every time you connect the BT device.
Hello.
I have installed the AOSP based ArrowOS and CrDroid roms and the audio lag on my bluetooth earbuds is considerable. According to the Audio Checker app, the latency is 244 ms, but in reality the latency has to be close to a second, especially when I'm using the Moonlight Game Streaming app.

However, in Miui or Xiaomi EU the latency is imperceptible. Audio Checker shows 80 ms of latency in these roms and in practice it is the same, I have even played Resident Evil 8 with bluetooth headphones and with a kishi connected to the mobile transmitting from my computer. The experience is good considering I'm using $30 Tozo T12 headphones.
As you can see in the attached images, in the miui based roms the audio buffer size is smaller than in the Aosp roms, at least that is what the Audio Checker app shows. So is it possible to modify some system file (I have root access) on those AOSP based roms to reduce bluetooth audio latency?
What Bluetooth Audio Codec is used on both? AptX? SBC?
The Codec makes a huge difference in the Sound Lag (and Sound Quality)
Ideally use AptX, if supported by the headphone

The app was last updated 7 years ago. I wouldn't trust its values too much..
But I've heard of other people complaining about significant Bluetooth Audio Delay in AOSP ROMs, compared to MIUI...
But does your Bluetooth headphone support AptX? You might be able to enable this in Bluetooth device settings.
Could try asking their respective Telegram Groups...
