Subject: Invalid PCM pointer with CMI8738 and pcm.c buffer underuns
Date: Wed, 26 Mar 2014 16:02:58 +0000 (UTC) [thread overview]
Message-ID: <loom.20140326T163743-253@post.gmane.org> (raw)
I've previously posted under ALSA's user mailing list so to avoid the
clutter, the details about what's happening is here:
http://article.gmane.org/gmane.linux.alsa.user/38258
http://article.gmane.org/gmane.linux.alsa.user/38260
There was no debug info under /proc/asound/card0/ so nothing to give from
there unless you guys need something specific.
Output of alsa-debug.sh:
