elx14,

I don't know if this will solve your problem, but could you check and see if the slmodemd daemon is running? If it is, try shutting it off and seeing if sound comes back. Also, as always, please double-check the devices in your mixer to see if they are set to "mute" or not. Sometimes, they do get reset unexpectedly.

Hello WeatherGod,

slmodem isn't running and i am checking one more time my alsamixer configuration... there is no change.
