ALSA: Pulseaudio loops writing syslog messages after suspend

English Hardware
#1

I am running alsa-1.0.18-8.9 and pulseaudio-0.9.12-9.5, currently the newest versions from OpenSuSE 11.1. The architecture is AMD64.

When I suspend the machine to disk and have it wake up again, in about 1 of 2 cases I get a pulseaudio process that is apparently in a loop writing the same 2 error messages to syslog, at a rate of 1413 messages per minute. The process is a standard userspace process that can be killed easily - once you notice something is wrong, which can take time unless you have a loud hard disk.

Here is a brief excerpt of the syslog messages (easy to guess how it is going to continue…):

May  6 08:01:00 hostname pulseaudio[11109]: alsa-util.c: Got POLLERR from ALSA
May  6 08:01:00 hostname pulseaudio[11109]: alsa-util.c: PCM state is RUNNING
May  6 08:01:00 hostname pulseaudio[11109]: alsa-util.c: Got POLLERR from ALSA
May  6 08:01:00 hostname pulseaudio[11109]: alsa-util.c: PCM state is RUNNING

Originally I posted this in the Pulseaudio Forum (Ticket URL: <#559 (Pulseaudio loops writing syslog messages after waking from suspend to disk) – PulseAudio](http://pulseaudio.org/ticket/559)) but was told it is an ALSA bug.

From the response in that forum:

This is an ALSA issue. Due to some reason ALSA signals us an error via POLLERR. We then try to reset the audio device via snd_pcm_drop() and snd_pcm_prepare() which seems to succeed but then results in POLLERR right again apparently.

My motherboard (with onboard audio, don’t know the chipset) is an Asus M3N78-EM AM2+.

I would be happy if this bug could be fixed.

Many thanks, Ned.

Wrong place to get the bug fixed, you need the alsa bug tracker for that.

You have this at the bottom that suggests it can be removed I’m not so sure and haven’t tried. I suspect it’ll try to remove half of your system.

PulseAudio - openSUSE

Shame it isn’t more up to date, hopefully someone else can tell you how to disable if the suggestion on the wiki doesn’t work.

A link to the alsa page for raising bug reports is here:
https://bugtrack.alsa-project.org/alsa-bug/login_page.php
… its a bit of a pain to use, because you have to “sign in for a new account” first, before you can raise bug reports.
