[alsa-devel] [CX2075] No sound after suspend/resume from front speaker
Hi,
this still seem to be an issue. After startup everything works well until the laptop goes to suspend.
Tried pretty much everything basic user can do (unmutes, rmmods and so on), still no way to wake the output. ALSA seems to be thinking, that output is active, you can set volume and stuff, but nothing happens.

The first thing to check is to compare alsa-info.sh outputs before and after the suspend.
Also pass snd_hda_codec.dump_coef=1 module option to enable the COEF dump. This will give more information in alsa-info.sh outputs.
