Hi,

I have tried many things to try to get my sound card to work, but no luck. At first with the when I started alsamixer, it would say that I have a generic sound card. My laptop has two audio interfaces: a nVidia HDMI and an IDT High Definition Codec. I read this mailing list and saw that many people had issues with the HP's version of the IDT sound card. Then someone added patches to fix an issue with DV4. The fixes were in the latest snapshots, so I did some searching and pulled the alsa sources from here: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git since I am using the 2.6.28 kernel. I went through the code and confirmed that it was updated to what I saw in the patches and the patches were not compatible with the kernel source I have, hence I was looking for something more compatible. More specifically, the kernel I have is "2.6.28-gentoo-r2 #5 SMP Wed Feb 25 15:37:22 GMT 2009 x86_64 Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz
 Genuine Intel GNU/Linux". With a little bit of work, I merged in the new alsa source with that kernel and recompiled. Things are detected a bit better, like now alsamixer is saying that I have the chip "Nvidia MCP78 HDMI" instead of a Generic one. However, this is not the chip I want. I want to output to my speakers and headphone ports. I tried setting the option "model=hp-dv5" and then "model=hp-dv7" but that does nothing. I have absolutely no sound at all out of my speakers or headphone port. The drivers for this soundcard are on the HP website if you need them.

Also, I tried removing the nvidia option from the list in the kernel configuration and only have IDT selected, but it would say unknow nvidia chip when trying to load the module on boot.

I have the output of lspci -nv attached to this email. I hope you can give me a clue as to what to do next.

This is what I have in my in my /etc/modprobe.d/alsa file:
# Alsa kernel modules' configuration file.

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
options snd cards_limit=1

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=hp-dv7 enable=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0


 I have a program that analyzed my audio in Windows. This is the output from that:
