[Bug 21574] Re: sound gone after resuming from sleep on hp nx8220

[Michel D'HOOGE]

Same problem with Dell Inspiron 630m (didn't try with headphones). However, if I change volume level or mute/unmute (through direct keys), sound is back. I also tried with 'amixer set Master toggle' but the results are not consistent: 2 toggling are not always enough and last time I tried 'speaker-test' it blocked after printing (the line "Rate set to 48000Hz (requested 48000Hz)" is never printed):
"speaker-test 0.0.8

Playback device is plughw:0,0
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise"

After another experiment I wonder if there is not maybe in addition a
timeout somewhere because speaker-test begins to work "suddenly".
