209843 – Buffer underrun from ALSA to pulseaudio using snd ...
https://bugzilla.kernel.org/show_bug.cgi?id=209843
Overview: ----- Running an application (a game) on the Raspberry PI 4 (64bits OS) causes the pulseaudio to crash with a buffer underrun. This is happening with some Godot Engine games. Steps to reproduce: ----- Run a Godot Engine game that produces many errors for a long time until the error happens.

Uninstalling pulseaudio-equalizer and editing /etc/pulse/daemon.conf to have a slightly bigger buffer (default-fragments=4 and default-fragment-size-msec=60) has reduced the clicking very appreciably for me, about 2-3 clicks per hour (every time a click happens, log fills with "underrun" and "rewind" messages, so the issue persists, just at a ...
PulseAudio: pa_buffer_attr Struct Reference
https://freedesktop.org/software/pulseaudio/doxygen/structpa__buffer__attr.html
Should underrun occur, the read index of the output buffer overtakes the write index, and hence the fill level of the buffer is negative. Start of playback can be forced using pa_stream_trigger() even though the prebuffer size hasn't been reached. If a buffer underrun occurs, this prebuffering will be again enabled.
PulseAudio: Audio Streams - freedesktop.org
https://freedesktop.org/software/pulseaudio/doxygen/streams.html
In case of a buffer underrun the read index is equal or larger than the write index. Unless the prebuf value is 0, PulseAudio will temporarily pause playback in such a case, and wait until the buffer is filled up to prebuf bytes again. If prebuf is 0, the read index may be larger than the write index, in which case silence is played.

My "buffer underrun" errors are gone, but performance in PlayOnLinux games are still poor. I have tried several solutions and its still not working in Mint 16 32-bit which uses Pulseaudio 4. I tried the tutorial, wine's suggestions, editing daemon.conf and even a custom .asoundrc script, but nothing works.

buffer underflows should not occur on at least one scheduling setting, and pulse audio should ask rtkit for new processes at a reasonable rate. Edited Aug 27, 2019 by Lauren Boley To upload designs, you'll need to enable LFS and have an admin enable hashed storage.

Posts: 1,570. Re: [SOLVED] ' (snd_pcm_recover) underrun occurred'. Pulseaudio has settings similar to alsas buffer_size, increase those. Refrain from using outside guides without understanding what you are actually doing, you probably should default your configuration for pulseaudio first, before attempting anything else.

24 minutes ago · It was properly audible and after a few days, I upgraded pip and underrun comes out of nowhere. I checked my hw_params and it showed closed. I tried to set the default fragments and buffer size, kill pulseaudio and restarted. For a few seconds, no underrun and later it occurs. I had tried several solutions in websites, but nothing worked yet.
