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?
