Hi,
Â
Since the upgrade to Alsa 1.1.7, I get a segfault at pulseaudio
startup. This have been discussed and documented here :
[1]https://www.linuxquestions.org/questions/slackware-14/current-fri-oc
t-19-puseaudio-segfauts-4175640773/
Â
It seems that I found the origin of the bug : reverting these 2 commits
fixes the problem :
[2]http://git.alsa-project.org/?p=alsa-...792dc809c908cc
[3]http://git.alsa-project.org/?p=alsa-...5dc6e1594291e7
Then no more segfault in pulseaudio when accessing the USB soundcard.
Â
Please could you fix it ?
Â
Regards
jp

It does not appear like a correct change, because rec->slave is
initialized in previous lines (snd_pcm_open calls). Could you inspect
rec->slave in gdb ?

Sorry, I have no more time to spend debugging :(
Â
Thus I guess that the true alsa maintainers will be much more efficient
than me (I'm just doing quick and dirty hacking here).
Â
My XMOS USB soundcard now works with this workaround, please could you
take a look at traces I posted in the discussion on LQ.org ?

All the best

Here is the better fix:
http://git.alsa-project.org/?p=alsa-plugins.git;a=commitdiff;h=a4e7e1282c57a2f4e83afe9a4008042d8b4c5bb9
There was really a double pcm free, because:
snd_pcm_ioplug_delete ->
snd_pcm_close ->
snd_pcm_ioplug_close ->
a52_close() ->
snd_pcm_close(rec->slave)
