High latency with headphone output - HTC 10 Questions & Answers

I am beta testing the new Poweramp V3 (alpha3 build-703) and using the Hi-Res Output (24 bit, 192 khz). It sounds really great, 5x better than the standard android API.
But I noticed that when I click "Info", I have 1687ms latency with the output with any earphones plugged in.
That is way too high because Xperia Z5 has 280ms latency over the same output (Pictures below!). Other phones with dac also have lower latency.
When playing music over the speaker, the latency is 100ms (normal).
Can someone please check his HTC 10 and see if he gets the same latency with Hi-Res output in Poweramp v3 ?
When at the song screen, you need to click the visualization icon, and the click the "i" icon to see the info.

I've noticed that as well, having no idea why the latency is >1000ms, even the "now playing" progress bar is going several seconds at a time.
PS: You may want to disable DVC and Headroom Gain(If you don't use equalizer), as when DVC is enabled on htc 10, the amplifier will be maxed out while PowerAMP use DAC to control volume, which will result in far worse signal-to-noise ratio unless you are at 100% volume.

You have 1687ms as well ? I hope that hasn`t got anything to do with hardware.
About the "now playing" progress bar, I have also noticed that, like there is a delay, probably a bug. --> When using the other 2 outputs, there is no delay, and the output latency is normal.

I do use equalizer (rock preset), I thought DVC gives you improved dynamic range, I noticed the sound is a bit better with it...

Latency here 160 ms.
ah, the second one is 1687 ms for me as well on output.
Keep in mind though this release of poweramp is highly unstable on my 10.
There seems to be no response from the poweramp developer, I've tried emailing him and his forum, all no go...

At least it is ~1700ms. Mine is at ~2800ms. Other than that, Poweramp works beautifully...

High frequency sound from speaker?

has anybody else noticed the high frequency sound(very high pitch) coming from the speaker when playing music from the music app, going to test from youtube etc now?
its more apparent on some tracks then others but for example on "Jay-z - kingdom come" (full volume) it gets to a point where i cant listen, there is a high frequency sound coming up and from listening to the song it seems to be there instead of the base. Not sure if its the terrible quality of the speakers, im on t-mob and i hear they limit the volume so could that be having an effect.
also let me add it can be like those teenage deterrent devices they put in shops where they play a high pitch noise only teenagers can hear , as with age the ear doesn't pick up as high frequency
testing out a bit , it sounds like instead of base there's a high pitch sound being emitted, is it my device , how is the music player on max volume on you guys devices?
Which device do you own? I have noticed something like that in my Acer Neo Touch S200... Have you found any cure?
No high-pitched noise from my Desire.
I've got this. I does it when the phone is on silent and it receives a text or call (something where a sound would normally be played)
I noticed it today. it seems to happen only when charging!

the sound that comes out in general is way too high in the treble department, unfortunately cant find a good player with a good equalizer to test out if its the phone settings or the speaker

Give astro player beta a go. It has an equaliser.
tried it out, im not sure if its just me or my phone, try a few songs out, high blast, ones with alot of base , see if you experience the same proble, there's a high pitch tone comming out along with the music, its most probz down to poor speaker, its the same issue on youtube,
i tried it with Jay Zs Kingdom Come, its very apparent

Quiet Audio from MX Video Player? Volume Boost?

Hello,
I've been using MX Player to play some previously encoded videos from Handbrake. The issue I'm having is that the audio is a bit too quiet to comfortable listen to using earphones or the device speakers.
I've adjusted the gain in Handbrake and performed some tests but the problem is to achieve a loud enough volume the Audio track from the video becomes slightly distorted in places which is extremely unpleasant.
Is there a way to adjust the N7's maximum volume or maybe a separate app/settings that may boost the output volume?
I've left my handbrake settings at Gain +5 but I'd still like the volume a little louder if possible. I have also checked that once ading gain to the video encode it was definitely the audio track that was distorted rather than the N7's output being pushed too far. I used the same video files on other playback methods and the distortion was still present.
Thanks
Volume 16-30 in MX Player should be a boost. If you're using 30 volume in MX Player and it's very quiet there must be something wrong with the handbrake settings(?)

Is Settings, Audio, Volume Boost enabled?

I also think you have to use HW+ decoding to get the volume boost capability.

Get the Noozxoid custom codec somewhere in this forum. Great tone and volume, especially when you plug it aux or earphones!

DAC Fix - Use the HI-FI DAC Everywhere!

Hi everyone! I've just developed an app that should fix the issue of the DAC only being usable in some apps.
Now the ESS DAC/AMP can be used in any app on your phone, including Google Play Music, YouTube, Spotify, and probably many more that I haven't tested yet.
Here's the Play Store link: https://play.google.com/store/apps/details?id=com.phascinate.lgv10.dacfix
It can be set to automatically turn on when the phone boots up. My goal was to make this a "set it and forget it" kind of fix. All you have to do is enable it once, and it should be fixed for good. Of course, I've only just released it so it may have some bugs. But so far it's working fine on my end.
If you have any issues or it's not working correctly, feel free to tell me here! Hope it works for you guys! I'm really loving the sound quality on this phone.
doing back up now so I can try this, very exciting news if this works
Seems like it's working in Neutron amp which has been my pain point ever since buying the phone.
Thanks!
*tested with youtube and DI.fm both seem working with the DAC with the fix
wow big deal, thanks
Tested with YouTube and XiiaLive Pro and the volume definitely changes when toggling the hifi option on and off.
It is working on Poweramp. Thanks.

Interesting... Can the developer tell us a little more about how this works? I really didn't think it would be as simple as an app like this making it work.

The concept is actually quite simple! Immediately when music starts playing, it plays some completely (and I mean completely! We don't want any background noise, do we?) silent media which tricks the phone into turning the DAC on.

Assuming things were bit perfect to begin with, will the signal still be bit perfect?

In theory, it should be. Because it's set to be silent, Android should simply completely skip over the silent media. In my own testing it doesn't seem to have had any negative effect whatsoever on sound quality. Though I'd love to see the frequency output in something like Audacity if anyone wants to test it.

Alrighty. Right now I'm on my lunch break at work listening with a Brainwavz HM5. Things seem good here, but I'll test tonight with my AKG Q701.
I really only use the stock music app and TIDAL which both worked without your fix, but I'll test everything out more tonight. My only concern would be a possible negative effect with apps that already worked fine, for example a silent track playing along with the regular music making things possibly no longer bit perfect, or extra battery drain for some odd reason. I'll test sound quality with my Q701 tonight and see if I notice any extra battery drain. All I can confirm at the moment is that toggling hifi on and off definitely changed the volume with apps that it didn't before.
Good work.

Yeah, that was my concern too. But everything seems to be working fine.
Feel free to post your results with the Q701's as soon as you test them!
Good job, works as intended. Thanks.
Few suggestions: Show status of app running in background from top pull down menu. Also the ability to enable disable from there. Otherwise still 5 out 5. :thumbup:
man you are a genious and this is the best ever app i appreciated this year
Does this app need root permission?
Edit: nvm. Just installed and gonna test..
Thanks for the effort mate. I'll also give it a try though as a non-audiophile person, I fail to notice Hi-Fi DAC effect anyway.
for those who can distinguish the difference between DAC enabled/disabled, can you tell that's even distinguishable with the QuadBeat headphones? I'm trying with some FLAC and various music players but other than then "higher volume" I cannot notice an improvement sound wise.
I do try with the QuadBeat and Bose QC25. I also just purchased a Piston 3. Do you think it's my headphones who are not enough to make a difference?
Can you maybe recommend a song where you can clearly distinguish the performance between DAC enabled or disabled?
Amazing app, thank you very much.
Now I challenge you to check the other audio limitation of the phone.
The normal and high gain mode of the Amp depending the impedance of the headphones at the moment is completely automatic.
That's OK with IEM but there are problems with big headphones with low impedance. In those cases the normal gain mode delivers not enough power (volume) and being able to select or force the high gain mode would be a perfect solution.
At this moment the high gain mode is triggered with headphones with an Impedance over 50ohm.
Thanks anyway for this app.

Seems to be no negative effects on SQ. Not sure on any change in battery life yet. Good so far.
Fantastic! At first I thought there would be a big battery impact since there is silent media playing, but then I remembered that only happens when there is actually music playing - fantastic implementation. Hopefully there is no battery drain. Works here for Google Play Music, so thank you very much!!!
it is working great with spotify here
I do notice the clarity with dac on and off.. however i'm using free spotify so the music stream is not high quality.
I only did notice a bug not sure because of this app or not but it never happen before.
So today i plug my phone to aux in my car in the morning everything work great.
in the afternoon i plug aux again to my car and this time my 4G or 3G writing on my signal bar is gone until i restart. This never happen before i install your apps, but seems i can't repeat this bug.
Firstly, thank you for taking the time to make this app. I just tested it with Player Pro and it seems to be working (Player Pro did work before but only if you didn't install the DSP pack). I did have one question. I noticed that the EQ is not working in Player Pro. You can open the EQ, but changing any of the frequencies or selecting a preset has no effect on the audio. Does that mean that the other audio features like Replay Gain also won't work with the app installed?

line level, nexus 6p

Apologies for the cross post, if you read the 6p forums you may have already seen this.
I use Chromecast audio for my home radio, it's a whole house intercom with a pretty mediocre amplifier.
When I cast via Google music it works great, but most apps don't support Chromecast audio, so I cast the whole phone via the quick settings tile.
On occasion this works well, but almost always the audio level is obnoxiously low, any good tips on boosting this? I'm currently unlocked but not rooted and running stock. I'll root for a solid fix, but would prefer not to.
If you root, AirAudio allows you to send any audio to any "cast" device. Demo is free, but has a time limit. You can adjust output volumes inside the app, but you can't over amplify (no positive gain, just max volume. I've not had many issues with it, as as far as I know, the volume at the phone and at the chromecast seem to be the same. (so if you have a mp3 at very low levels on the phone, it'll be low level at the device, too.)

General Audio driver problems

So wanted to comment on this
First, this is the best phone I’ve ever owned, although its lacking in a couple of things i was used to (coming from a oneplus 9 that had a lot of settings compared to this one, still this is a waaaay better phone) the speed, screen size and battery life makes it all worth it
Though! I use a lot of external dacs through the usb c connector (main reason to have a big battery)
I’m finding some issues in the audio department:
Tidal mqa files are not being played if the dac doesnt have mqa decoding (normally they would play without issues in iPadOS and one ui/ oxygen os
Some dacs (specially ifi hifi link) will not play files until a mqa file is played, though any system sound will interrupt the communication with the dac, it can be fixed played any master quality track and then going back to flac/ hifi quality in tidal, YouTube doesn’t work at all with this dac.
Facebook and YouTube wont play audio sometimes,my theory is that the player goes for the oem 3.5 out instead of the dac. That could be fixed if we got an audio output selector in the notifications player, though the option is not available as the player plays as a simplified notification, so no audio selection is possible
Of course the 3.5 jack in this is quite nice but … usb c dacs are a bit better at handling hi res files and streaming and of course demanding headphones.
Sent already this to nubia. Hopefully there will be a work around, UAPP is a viable solution of course but the easiness to surf through playlists is better in the tidal app.
So anyway, anyone surfing for an answer: its in the developers hands
Just wanted to leave this in case anyone looking in the internet is looking for answers on this
No audio switch app works on android 13 (lesser audio switch, etc)
Although there’s work around for using the external dacs, it comes as a surprise the first times. Though the phone is a beast and i truly love the battery life and extended display, a couple of tweaks and this would be the best phone out there
Kinda figure it out. The DTS ultra app was the culprit, even if it showed the toggle off, it was turning on (and screwing the sound for me) , just disabled the "auto start" or link button on the app preferences. all audio is being processed by the external dac. At least YouTube and fb are working flawlessly so far
Update: Some dacs are still having issues with the mqa decoder, but the general audio is coming out of the usb c port at least.

Hi there. I had the same problem. But I was able to access my DTS Ultra app. It doesn't appear in my app drawer but I found the audio effects app for DTS Ultra using Activitylauncher from play store.
I could be wrong but I also noticed there is no way to EQ the speakers on the phone. The DTS Ultra app only shows up for headphones and gives the "Disconnect External Devices" error on speakers. I find the speakers to be good quality but slightly lacking in tuning, is there any way to perhaps tune them through 3rd party means? Thanks for the help.
