31 After running "alsactl init" the only settings muted in "alsamixer" are
32 "Master" and "Headphone", and yes, I can unmute both by pressing the "m"
33 key. But this does neither bring back sound nor does it change the out-
34 put from another "alsactl init".

40 Oh well, is there a replacement for ALSA? Can I use "pulseaudio" with-
41 out ALSA?
