I dont know it is a problem about alsa drivers, nvidia driver ... any clues?

my alsa-conf is

alias snd-card-0 snd-hda-intel
#options snd-hda-intel model=auto
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1
#options snd-hda-intel model=3stack-dig
options snd-hda-intel model=3stack


and nvida propietary drivers is 260.19.29 lastest

what can i do ?

thank you
