sound card problems

[Francesco Pietra <chiendarret@gmail.com>]

Hello:
With Debian amd64 wheezy I was unable to get the sound card working
correctly (bumping voice or sound) for a Gygabyte GA-X79-UD3
motherboard, while with  other motherboards there are no problems.


:~$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation C600/X79 series chipset High
Definition Audio Controller (rev 05)
02:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller (rev a1)
03:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller (rev a1)

:~$ cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf9120000 irq 72
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfb080000 irq 17
 2 [NVidia_1       ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xf9080000 irq 17

As far as I can understand, Intel is chosen by the system, while I
should change to NVIDIA.

I found some suggestions how to make NVIA card first choice but they
did not work.

Thanks for help
