Re: [alsa-devel] Invalid PCM pointer with CMI8738 and pcm.c buffer underuns

Seem cannot read valid value from register within three trials

state.CMI8738 { control.1 {

[...]

Seem bug in adding channel map to iec958 instead of analog

What does that mean? What should I do with those patches? Should I apply them and try to compile the latest ALSA version?

pcm.!default { type plug slave.pcm "dmixer" }

You need asym plugin for playback and capture when overwrite pcm.default

Should I change my /etc/asound.conf like in the examples here? http://alsa.opensrc.org/Asym
