Please note that the upgrade to Store wsl worked like a charm, and my linux GUI apps work flawlessly.

Same here. I get this with most RDP really, but this is particularly bad, which makes no sense for something that's entirely local. I have my own reasons not to upgrade to Windows 11, and am very glad that these things are available on Windows 10 now. I was planning to make use of emacspeak in wslg as I'm a blind user, but I can't go half a second without jitter, pops and clicks, or some kind of ring modulated garbage due to buffer underruns. Even with something as simple as running espeak-ng and typing some text into it. I should note that my tests so far haven't actually spawned a GUI, but the subsystem seems to activate anyway. Using pulse audio I believe. This is Ubuntu 22.04, fresh install after the store upgrade, with systemd.

Same here: Windows 10, WSL2 updated to latest. GUI apps work but playing an mp3 file in vlc stutters

Seeing this same issue on a fresh install of Ubuntu 22.04 under the latest WSL. Added libpulse0 as noted in microsoft/WSL#9192 to get audio working at all, but playing flac files via cmus leads to stuttering audio. The same setup on Ubuntu 20.04 works correctly.

Same issue.

[Dai-JiaLin]

Same issue. Is there any solution?

Also encountering this with terminal audio apps (e.g. ncspot) on Windows 11, so I don't think this is strictly related to GUI

Same issue, CMUS and VLC sound is sluttering, but mpg123 sounds perfect, don't know why

Just did this, and now it works great
sudo apt install pulseaudio pavucontrol -y
pavucontrol is a GUI, so you may not need it

[e1uone]

Nah, problem still persist in CMUS, but VLC is acting strange, i'm getting corrupted audio for about 10 seconds, and then it "repairs" itself

I've also got this issue in WSL2 in Ubuntu. I am trying to play an audio file using the miniaudio.h c library. It manges to play fine for about 29 seconds and then the audio becomes very choppy. You only hear a little note every one or two seconds. I have replicated this issue with cmus too.

Audio clips below 29 seconds seem to work fine. Any idea what might be causing this?

I am on Windows 11

Only could get it working with ffplay so far, same issue with vlc

Just did this, and now it works great
sudo apt install pulseaudio pavucontrol -y
pavucontrol is a GUI, so you may not need it

For me installing pavucontrol fixed the choppy issues. It would come back if I leave WSL running for a long while. But then restarting WSL fixes the issue.
