Try to manually modify the sound module parameter like described in this post:

After giving up on the problem and coming back I rediscovered this thread, I have tried adding lines to the /etc/modprobe.d/alsa-base.conf file so many times now that i dont know what the original was like anymore.

I also have no idea how to manually change that parameter...
