Alex, does the patch in #165947 fix this?

Comment 3 Alex Duggan 2005-02-15 03:52:00 UTC

Ronald,

I just upgraded to gstreamer, gst-plugins and gnome-media cvs head.  I tested
with an without your patch and the same result happened.

If you open gnome-volume-control and don't change any settings and then launch
bmp, it will play just fine.  If you change a setting in g-v-c while a song is
playing, g-v-c will segfault when you close bmp.

If you change a setting in g-v-c and then launch bmp, g-v-c immidately segfaults.

Applying the patch does not prevent the crash.

I see this at the command line:
nome-volume-control: simple.c:1441: snd_mixer_selem_has_playback_switch:
Assertion `elem->type == SND_MIXER_ELEM_SIMPLE' failed.

Comment 4 Ronald Bultje 2005-02-15 08:26:34 UTC

Can you get me SSH access to your computer? I know it's weird to ask, but I've
seen this report 4 times now, so it's not just a local thing. I don't have a
SB!Live, and apparently that's the only way to reproduce it...

Alex, can you apply this patch and tell me what it says (assuming it says
anything)? If it says something, I at least know what the problem is (and acn
hopefully fix it).

another one

Since the previous one didn't give what I wanted, here's another one. Does this
give better output just before the crash? Thanks.

proposed patch

I think I know how to do it now. Attached patch should fix the crash, at least.
Alex, please test.

Comment 8 Alex Duggan 2005-03-03 14:26:16 UTC

Ronald, I'll test this tonight for you.

Comment 9 Alex Duggan 2005-03-04 05:12:44 UTC

Ronald, this fixes the crash, I can't seem to reproduce it under any of my
normal circumstances.

Comment 10 Ronald Bultje 2005-03-04 08:37:16 UTC

Marking as blocker for 0.8.8 release, which is already in testing phase...

Comment 11 Thomas Vander Stichele 2005-03-05 16:32:48 UTC

commited, closing.
