just a shot in the dark...this is my modprobe.conf file.I had to add the 
option model=acer to have sound working.
Google is your friend in order to find what is your option

alias eth0 tg3
alias scsi_hostadapter libata
alias scsi_hostadapter1 ata_piix
alias scsi_hostadapter2 ahci
alias scsi_hostadapter3 usb-storage
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0 model=acer
