Ljudet har slutat fungera på min laptop

[Bacillen]

Ljudet har slutat fungera på min laptop. Har fungerat klockrent innan, men nu är det heltyst.

Kan någon hjälpa mig att felsöka för jag vet inte var jag ska börja?

Först en liten uppdatering,
när jag ansluter en extern högtalare och drar upp ljudnivån till max så hörs ett susande i högtalaren som försvinner när jag sänker volymen.

Här kommer en utskrift av lsmod

Ljud är inte min grej men har du kollat reglagen i alsamixer?

[Bacillen]

Jag körde en reboot av datorn och då funkar ljudet igen??!!!??

Har tyvärr ingen aning om vad jag gjort.

Tack ändå
