Public bug reported:
The following taken from URL
http://www.alsa-project.org/main/index.php/Matrix:Vendor-Creative_Labs for the
Sound Blaster 5.1 VX describes the problem.
On the VX, white noise on playback unless initialized in Windows first. One
quirky (but permanent) workaround is to enable the old oss modules,
specifically the 100% sound blaster compatible module (sb). You don't have to
load the oss modules. The alsa module snd-ca0106 works fine somehow if the old
sb module is compiled in the kernel as a module (no white noise).
I would like to apply the fix as stated but I will need detailed instructions
on how to do this as I am a new Linux user.
