Jel imas sad ideju?

Čudno, na tom laptopu zvuk u Ubuntu ladno bi trebao da radi, bez ikakvih podešavanja. Čak i u Live režimu sa CD-a!
Edituj, kao root, fajl /etc/modprobe.d/alsa-base
i na dnu fajla dodaj sledeći red: options snd-hda-intel model=laptop

Restartuj linux, i trebao bi zvuk da radi.
E sad, ja imam HP 6735s, i instaliran Debian, i kod mene ovo radi OK.
Jedini problem može da bude to što Ubuntu tera pulseaudio, a Debian alsa drajvere.

Za pocetak - jesi li pogledao u Mixer-u, da li je sve pojacano?

(klik na zvucnik dole u panelu, pa na "Properties", pa ukljucis sve kanale, pa ih pojacas)

Gore sam pojacao na soundu kanale ni to ne pomaze.Volume,line in,microphone i.t.d sve sam podigao.
