Re: nForce2 CPU C1 Disconnect Hang Fix (Semi-Official)
Yes, the same patch applies for both 2.4 and 2.6 kernels.
Sorry, I don't know about the onboard sound as I use a SB Live on my Asus A7N8X instead. However, I didn't think the OSS i810 and nVidia drivers could provide multiple inputs channels as its a hardware limitation (i.e. 1 only), isn't it? Are you sure you didn't have a sound daemon running previously?
