Hi,

Since my latest Slack Current update Fri Oct 19 pulseaudio segfaults with new alsa 1.1.7.

rollback to alsa 1.1.6 fixes the problem.

I have no time to troubleshoot this right now ...

Cheers
JP

Pulse audio working just fine here after October 19th update.

What programs are you running to cause this segfault? How are you running them? There is just not very much info to go on making it hard to be more helpful...

I have been running voice chat in discord, listening to music in spotify and pandora, and streamed netflix, and a DVD from my Samba share without any problems with sound. I have not made any changes to pulseaudio configurations. Running the latest -current as well.

Standard config working with alsa 1.1.6, default pulse config.

Below with new ALSA 1.1.7, default pulse config, bluetooth disabled :

I will make tests with a standard sound card instead of USB direct attach to my ALIENTEK Digital Amp, to check... but it's really looking like a serious regression in Alsa 1.1.7 : worth a rollback in Slack current :/

orbea · 10-20-2018, 01:15 PM

Ideally someone could use git to bisect to what alsa commit caused this issue, but that would require someone who can reproduce the issue to do the work.

Also rebuilding with debugging symbols and getting a backtrace with gdb could maybe help an alsa developer figure out this issue.

Alternatively its possible to roll back alsa, but then it may never get fixed if no one else has the right software and / or hardware combination to trigger it or if those who do also never do the work to figure it out hoping that someone else will...

dugan · 10-20-2018, 01:21 PM

I have a USB sound card too (well actually I own two, but I use one all the time), but I'm planning to wait a couple more weeks before updating.

I'll give you my report then.

would be fair to do a quick test..

H1p8r10n · 10-21-2018, 02:39 AM

I confirm the bug is with USB soundcard only.

Internal soundcard doesn't make alsa/pulse to segfault, plugging USB soundcard in makes pulse to segfault immediately

Hi,

It seems that I found the origin of the bug : reverting these 2 commits fixes the problem :

http://git.alsa-project.org/?p=alsa-...792dc809c908cc
http://git.alsa-project.org/?p=alsa-...5dc6e1594291e7

No more segfault in pulseaudio when accessing the USB soundcard !!

Could this be reported to upstream and patched in Slackware waiting for alsa devs to fix the bug ?

Thanks
JP

I have narrowed to the simpler patch below :

Hi,

Following my discussion on the alsa-devel mailing list, the problem has been officially fixed in alsa-plugins master GIT.

It could be patched in Slack waiting for next alsa release... so that we can mark as SOLVED

Edit : I just noticed that Pat has applied my previous fix to current. The official alsa devs team fix is better imho

sorry for the waste of time :/
