Ok, that looks ok (although I have some mixer questions). It still confirms your hardware as an Codec: IDT 92HD71B7X
That also looks good. I assume you restarted your PC afterward? (after both the alsa update, and after the change to /etc/modprobe.d/sound file ) ? And you are using the speaker test I recommended? Please try the following two speaker tests as both a regular user, and with root permissions …
speaker-test -Dplug:front -c2 -l5 -twav Note Linux is case sensitive, and “D” is not the same as “d”. Note you should check your mixer settings (kmix if using KDE, and alsamixer if using Gnome) to ensure that PCM and Master Volume are set around 95%. Note the test for surround sound is different. If that test yields errors, try instead this more simple test: speaker-test -c2 -l5 -twav
OK, syntax is correct there ad the file looks correct. You could try that without the “enable_msi=1”, … ie try:
options snd slots=snd-hda-intel
options snd-hda-intel model=hp-m4
# u1Nb.uI7Vp9nVK5B:82801I (ICH9 Family) HD Audio Controller
alias snd-card-0 snd-hda-intel
and restart your PC and test your sound.
Reference your mixer, I am not clear if the following have effect on your sound:
!!Amixer output
!!-------------

Front Left: Playback 64 [100%] [0.00dB] on]
Front Right: Playback 64 [100%] [0.00dB] on]Does toggling those OFF have any effect?
Now you could also try changing “hp-m4” in the /etc/modprobe.d/sound file with one of the other options listed in the HD-Audio-models.txt file … ie that documentation file lists:
STAC92HD71B*
============
ref Reference board
dell-m4-1 Dell desktops
dell-m4-2 Dell desktops
dell-m4-3 Dell desktops
hp-m4 HP dv laptops
and hence you could try “ref”, or “dell-m4-1” or “dell-m4-2” or “dell-m4-3” instead of “hp-m4” (one at a time, restarting your PC with each attempt, and also checking your mixer and noting the sound test recommended).
Please also confirm your sound is switched ON in your laptop’s BIOS.
Does sound work under Vista or WinXP ?
