13 Probably those are HDMI and 'normal' device. I had similar problems on my
14 sister's PC.

26 My solution was to edit /usr/share/alsa/alsa.conf, and change
27 defaults.ctl.card and defaults.pcm.card from 0 to 1. Add this file to
28 CONFIG_PROTECT in make.conf, or else the next alsa update will overwrite
29 the file.
