Audio renderer error when switching between 2 separate videos

[dag-h]

Version info:
qutebrowser v1.13.1
Git commit:
Backend: QtWebEngine (Chromium 80.0.3987.163)
Qt: 5.15.1 (compiled 5.15.0)

Does the bug happen if you start with --temp-basedir?:
Yes

Description
Playing a second Youtube video in another tab or browser instance gives me "Audio renderer error. Please restart your computer". Refreshing a few times finally makes the video play, but going back to the first video gives me the same error again, a behavior which repeats every time I switch between the videos. The same behavior when watching streams on Twitch.tv. I'm on Void linux using PulseAudio.

How to reproduce

• Open Qutebrowser with qutebrowser --temp-basedir
• Go to https://youtube.com/
• Go to any video, pause it or leave it playing
• Open a second video in another tab or browser instance
• Play the second video

This is unlikely to be a qutebrowser issue - can you check if you see the same with KDE Falkon and/or Chromium?

[dag-h]

Experiencing the same issue in Falkon, with the same error message in the logs. Chromium works without any issues.

Closing this then - I suspect it's some Voidlinux-specific issue similar to the one mentioned here: https://old.reddit.com/r/qutebrowser/comments/iy00k6/suddenly_no_sound_in_qutebrowser/

You might want to report this to Void instead.

@Harjuu Have you found a solution? I'm having the exact same problem. Also on Void Linux.

[dag-h]

@minikN Unfortuantely not. I've had so many audio issues in void that I'm thinking of switching back to Arch or something lol.

[minikN]

Really? Can't say the same thing. I've had issues as well sure. But I think most of the time the problem isn't the problem itself, but the lack of documentation. However up until now I've been able to fix every issue so far. On the other hand a lot of things are easier on void compared to other distros.

But off topic. I checked with a couple of other browsers and I only have this issue in qutebrowser. Really none other. So I'm just gonna switch until this has been fixed.

[The-Compiler]

@minikN Did those other browsers also include something else based on QtWebEngine, such as KDE Falkon?

[The-Compiler]

Let me note that Void Linux patches in a completely new audio backend (sndio) in their QtWebEngine package: https://github.com/void-linux/void-packages/tree/master/srcpkgs/qt5-webengine/files/sndio-files

That is also the default being used from what I can tell, so given that this only affects Void Linux users I'm pretty sure the culprit is in those void-specific patches.

FYI for all: As noted in IRC, I'm attempting a qtwebengine rebuild with Void's sndio support turned off, and I'll report back whether I can still repro my flavor of the issue (where qutebrowser/qtwebengine is bypassing PulseAudio completely and taking exclusive control of the sysdefault Alsa card (which is onboard laptop sound on this particular machine))
