[alsa] mixer crash in snd_mixer_selem_get_playback_switch
Last modified: 2009-07-27 21:25:02 UTC
What were you doing when the application crashed? I had the "Preferences" window open, and switched the sound card to control from my modem to my "normal" sound card.

We still need a decent stack trace for this. If anyone can reproduce this, please let us know. Also, in the gst-plugins-base versions used here the gst_mixer_*() API didn't have any entry guards, so it was possible to pass in already-freed mixer tracks, for example. This has been fixed meanwhile, but may or may not be related to this bug.
