Problems with nvidia sound card

[Itxi_Atea]

Hello everybody,

my nvidia card is being detected as the default sound card in alsa's configuration making the onboard sound card useless so I need to disable it.

I found a lot of solutions, first (as related here: https://forums.gentoo.org/viewtopic-t-896396-start-0.html) I can blacklist the nvidia sound module but checking it I found that both cards use the same module.

I tried to change the default card following the process in this post: https://forums.gentoo.org/viewtopic-t-819538-start-0.html but it doesn't solve the problem.

The last solution I tried is this: http://hennr.name/2011/06/29/how-to-remove-nvidia-hdmi-sound-cards-under-linux. I succesfully removed the device(lspci confirms it) but then alsamixer is not accesible and I cannot change the settings so I don't really know if the problem was solved. At this point I also set the command to be executed at gentoo start but it seems that it's not working, lspci continues detecting both cards,

Any suggestions?

Thank you very much.

I use probe_mask=1, to ignore the nvidia "soundcard".

Google for probe_mask.

So I added an otion to /etc/modprobe.d/alsa.cfg

I don't really know how but after a kernel recompile changing some parameters It is now solved. I changed the parameter
