sound disappearing

[VladimirMrzv]

I am streaming video from games. Before i used virtual card from pipewire. Now trying this plugin, but after 3:30 minutes sound disappearing.

https://www.twitch.tv/videos/1533647249?t=0h3m17s from 3:30 no sound

Trying change input source, but not help. And no indication for sound in mixer.

This may take a while to fix because it's happened to me before but it's very hard to reproduce since it's rare and random. What version of PipeWire are you running?

[VladimirMrzv]

I am on Ubuntu 22.04 pipewire 0.3.55 from https://launchpad.net/~pipewire-debian/+archive/ubuntu/pipewire-upstream

[VladimirMrzv]

I can help to reproduce it and save log. Write please how to do it.

[dimtpap]

I generated a 3 hour audio file and let it run in its entirety two times, the stream never stopped. If you can reproduce it run pw-dump > pw-dump.log in a terminal and upload the pw-dump.log file here, thank you

Here's my pw-dump.log after the same issue. I can't reproduce it at will but it only takes a couple of minutes to happen on my PC so if there's something else I can do identify the issue let me know.

pw-dump.log

New sources work, but the one that has this issue stops doing anything, even after changing the application or checking "Capture all apps except this one".

I'm running Pop!_OS 22.04 LTS, OBS 27.2.4, pipewire 0.3.53 and version 1.0.4 of the plugin.

[dimtpap]

What are the outputs of journalctl -e --user-unit pipewire and journalctl -e --user-unit wireplumber? Also does it occur consistently after a few minutes?

I forgot to mention it in the first post, but I think I've only tried using the plugin with games using Steam Proton so far. The application is wine64-preloader, which all Steam games seem to show up as when running them through Proton. The game the OP was playing doesn't have a native linux version, so I believe they were using Proton as well.

For today, the first is

-- Boot 20c48f78746748a19eb15919084990aa --
heinä 18 14:25:23 pop-os systemd[3225]: Started PipeWire Multimedia Service.

and the second

-- Boot 20c48f78746748a19eb15919084990aa --
heinä 18 14:25:23 pop-os systemd[3225]: Started Multimedia Service Session Manager.

I've triggered the issue today twice around 1-2 hours after the latest timestamps in the logs. It seems relatively consistent, I have not had it working continuously for more than maybe 10 minutes.

I've had it happen with native programs like Firefox and Discord so Proton/Wine is not related. Whenever you can, run OBS through a terminal using this command PIPEWIRE_DEBUG=5 PIPEWIRE_LOG=pwlog.txt obs --verbose. When the sound stops, post the pwlog.txt file, it will be in the directory you ran the command in

[VladimirMrzv]

my files pw-dump.log pwlog1.txt pwlog2.txt

I run game from steam in proton. Reproducing in Dying Light 2.

[dimtpap]

This isn't guaranteed to fix the problem since it's so annoyingly random, but see if this build fixes it. Install it like you would install a regular release, replacing the installed version you have

Edit: If you want to manually build it here is the patch

[VladimirMrzv]

sad, but not helped

New logs pw-dump2.log pwlog6.txt pwlog5.txt

in file 5, after start no sound and plugin not work

[Heliozoa]

Hard to say for sure if something's fixed for sure with a random issue like this, but I had the plugin running using the build above without issues for 4 hours, compared to before where it would consistently stop working within 10 minutes.

edit: Nevermind, it broke again with a different game. It almost feels like it works for hours with some applications and breaks in minutes with others. Here's my pwlog.txt

[VladimirMrzv]

Try on another game and it works 3-4 hours. Maybe something go wrong with Dying Light 2.

Hello here! I'm facing the same trouble too. Also using wine but other sounds sources vanish after some time too (firefox & discord already experienced). Will try to generate log on a future session.

[dimtpap]

Playing around with the properties and taking a look at PipeWire's source code I could get the stream to not process when ALWAYS_PROCESS was set to true. From some quick and dirty searches on their GitLab it looked like these options just affected which driver the stream was set to follow. Setting both this and WANT_DRIVER to false hopefully prevents this behavior.

Try this build from commit 0b895f5

[aeris]

Nice, i will try that soon!

[VladimirMrzv]

After update pipewire and today plugin it works better, but sound continue disappearing in DayingLight2. Now disappear after 1 hour and 25 minutes, it happened two times - 5 days ago and today.

[dimtpap]

Let me know if this is happening with PipeWire 0.3.59

[aeris]

No trouble here since last release and during 4-5h session. Will try it soon with 0.3.59.

[DonKatsu]

OBS 28.1.2, obs-pipewire-audio-capture 1.0.5, Pipewire 0.3.60 from the Fedora repos Application Audio Capture with Monster Hunter Rise (wine64-preloader selected) is consistently losing audio. Haven't tried anything else yet. Here's a log but I likely didn't catch it exactly after it happened. pwlog.txt

[dimtpap]

Great news, after narrowing down the issue and reporting it to PipeWire it got resolved rather fast. I'll test it and I will close this if it's fixed. Thanks everybody for your help!

[dimtpap]

All good! I'm expecting the fix to be included in the next PipeWire release, 0.3.62

[luni3359]

Thank you so much! I'm very glad it got solved
