Daniel,
This did happen again. The same workaround did not work this time.
Attached, please find:
lspci.txt (lspci -nv)
tail-sndstat.txt (tail -2 /proc/asound/oss/sndstat)
amixer-before-workaround.txt
amixer-after-unsuccessful-workaround.txt
amixer-after-new-workaround.txt
Steps:
1) bootup
2) The sound was not functioning (amaroK appeared to play but no sound).
3) I did the lspci -nv
4) I did the tail -2 /proc/asound/oss/sndstat
5) I did the amixer
6) tried the headphone workaround previously mentioned <- did not work
this time (no sound in amaroK still)
7) shutdown and power off
8) powered back on
9) still no sound (no sound from amaroK)
10) tried the headphone workaround again < - still no sound
11) stopped amaroK from playing started stopped - still no sound
12) sudo cat /dev/urandom > /dev/dsp <- produced white noise
13) started playing in amaroK and sound was produced.
14) ran amixer again to capture the final txt file.
It seems that sound may be somewhat unstable recently?
