Re: Why and how to blacklist soundcard or networkcard modules?
Now i have the same problem with sound. I also have an Yamaha sound
card which i rather use then the via on board chip, but when i use
the Yamaha card and boot the pc alsa has configured the via chip, when
i then connect that via-output to my audio set and reboot alsa wants
to use the Yamaha card.
You can choose and configure the Yamaha card (if you are using Alsa)
using alsaconf. This certainly worked for me in Etch. The configuration
survives reboots and output is no longer directed to the onboard sound
(sections 3 and 4).
