LDAC Choppiness/stuttering

[trip6kitty]

I noticed that when I use my Sony WFXM4 ear buds that have LDAC, while listening with LDAC the audio will come very choppy and stutter.

I know turning off LDAC resolves it, but of course I want to listen with LDAC on.

I recently tried turning off Wavelet when experiencing this issue and that also fixed it (but of course I want to listen with wavelet).

I noticed that I experience the issue more when the phone is locked and not in use. The issue sometimes goes away when I unlock the phone and use it.

Are you aware of this issue?

I have a Pixel 6 pro on Android 14 beta 1, but I have experienced this issue for a while when also on Android 13.

Thank you. Please let me know if you need anything from me and I will be able to assist.

I can confirm this behaviour too. I have a Pixel 6 on Android 14 (Stable) and I am using the FiiO BTR5 2021

I've tried replicating the issue but without success. WH-1000XM4 headphones and Android 14 on a Pixel 7 and Android 12 on an LG V50. Which settings do you have enabled, and to what value is the buffer size set to?

[Azel04]

I just have AutoEQ enabled (Moondrop Aria Snow Edition profile) with 4096 samples.

I'll try to replicate the issue again (perhaps it got fixed with the Android 14 November Update?)

[trip6kitty]

Buffer size was default. AutoEQ enabled for WF XM10004 and Graphic Equalizer set to V shape.

I have since got a new phone and the issue is gone (I now have a P8 Pro).

I had found a cause and workaround though, in my anecdotal experience. If I started listening to music on one app (e.g. Spotify), then switched to another (e.g. Poweramp), I would experience the issue when the screen is off/locked. To fix it, I would have to kill the first app (Spotify). So I unlock, swipe down notifications completely, then at the bottom where it says "2 apps are active", I would open that then kill the first app (Spotify). I have found it doesn't matter what the app is, I have experienced it with Spotify, Poweramp, Soundcloud, and Youtube. The resolution is the same: kill the app that I am no longer listening to.

I can confirm what you said here.

Having 2 Apps open (in my case Spotify and Synfonium) and then turning the screen off results in choppiness/stuttering with LDAC.

Killing one of the apps fixes the issue.

[trip6kitty]

Strangely it only happens on P6 Pro. This does not happen on my Pixel 8 Pro. Both are on the same version of Android.

I have a Pixel 6... Weird

[hmnd]

I'm experiencing the same on Android 14 on a Pixel 7 with WH1000-XM3 headphones. Can confirm @trip6kitty trick of killing the app no longer in use fixes it :thinking:

[ElfyTR]

I have the same issue with the wh-1000xm5 and galaxy buds 2 pro even wrote a issue too has anyone been able to solve this

[jhodgdev]

Experiencing the same issue on Wavelet 23.09

• Google Pixel 6 Pro
• Sony WH-1000XM5 w/ incl. AutoEq profile.
• Occurs with buffer size at 4096 and 8192 samples.
• Choppiness only occurs when phone is locked.

Killing apps so only one is using Wavelet --- in my case, YouTube and Pocket Casts --- does resolve the problem.

[NielsMayer]

Instead of killing other apps, what about turning on "power saving exclusions" for wavelet and any media players that might get put into "power saving mode" especially beginning with Android 13 and 14...

......

some notes I wrote on this topic:

https://hyperionics.com/atVoice/stops.html

Note "@ voice" app launches the "power savings exclusions" settings directly on clicking "continue" in the second dialog after clicking "continue" in the first.

"Android P There’s a special option in Settings > Apps > Your app > Advanced > Battery > Background restrictions. If users accidentally enable this option, it will break their apps. And users do enable that option!

Pie and pre-Pie If you see background processing issues, overall it is a good idea to make your app not battery optimized to ensure it gets the freedom it needs to perform in the background.

For that:

Go to Settings > Apps > Your app > Advanced > Battery > Battery optimization

Change view to All apps

Search for your app

Choose Not optimized

Android O Make sure Settings > Apps > Your app > Advanced > Battery > Background limitations is not enabled. If the app is not yet optimized for Oreo API level it will break their background processing."

Revisiting this as I recently got WH XM5s and was running into this issue again. The "workaround" I commented on 11/14/23 still works, however the comment by @NielsMayer reminded me to check the battery restriction of the Wavelet app. I saw that it was set to Restricted. Once I set to Unrestricted, it appears to have fixed the issue. I am able to keep Spotify and Poweramp open, and switch between playing music between each app without killing the other.

Edit: issue was not actually resolved. Issue returned on next audio session even with Wavelet restricted.

[NielsMayer]

@trip6kitty -- This issue really shouldn't be closed. Has a mechanism been added to check the status of battery-saving and pop a dialog warning the use, similar to what the " @ voice" app does?

My comments (pasted from my existing notes on the issue) and the arrived-at workaround were posted here because I am also facing the need to fix this issue in my own app.

I'd also like to get opinions from the developer @Pittvandewitt and other users on the correct way to go about fixing this issue in an app that might target a wide range of devices and types of devices. For example Android TV seems to handle this kind of thing differently, given that "TV" typically runs with line power. However, if the app is intended to run in the background, that could impose other similar issues.

Discuss. :-)

[trip6kitty]

Yes I didn't realize that I would close the issue upon commenting.

Also I saw that my issue was not resolved either, as even with Unrestricted battery usage on Wavelet the issue came back.

I'll reopen the issue.
