I have an HP DV6-1030ca, I could get sound with an alsa fix in F11 by creating an /etc/modprobe.d/alsa-base.conf with 'options snd-hda-intel model=hp-m4 enable_msi=1' but his no longer works in 12, I have tried every incantation I could scour on the net for some time. Anyone got a hint? Thanks! jlc
