[Bug 2063255] Re: Cannot play audio from server on older models
Another interesting data-point: apparently mpg321 *isn't* broken on noble. It works, but only with the headphone output (on those models that have it, i.e. everything prior to the Pi 5). Same goes with ffmpeg; no buffer xruns when outputting to the headphone socket. Which leans me back towards "something iffy with vc4hdmi and ALSA"... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063255 Title: Cannot play audio from server on older models To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2063255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2063255] Re: Cannot play audio from server on older models
Hmm, I may have to revise this. It seems mpg321 (with ALSA, which is how I've always tested the audio output) just doesn't work at all on any model; just complains about libao driver everywhere. Meanwhile, ffmpeg (my backup) works happily on the 4 and 5, but just complains about buffer xrun errors on all the earlier models (and takes a bizarrely long time to respond to ctrl-C when it does). However, aplay (ALSA's own userspace utility) works happily, at least on the 3B+ where I tested it, but only plays WAV or PCM, not MP3s, which just adds more complexity to the testing script. Still, that *suggests* ALSA's operating correctly and perhaps it's just ffmpeg trying to allocate a buffer that's too small to avoid overrun on the older platforms (and mpg321's presumably just broken on noble). I'll leave this open for now, but I'd advise the kernel team to ignore it while I dig a bit deeper. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063255 Title: Cannot play audio from server on older models To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2063255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
