Re: PC speaker driver

I'll show my support for this too.

I guess it's also these machines that get locked up in a closet that it's
fun to have something like this on when it doesn't deserve a real
soundcard (till I buy one... but this will save me some cash till then). I
also suppose pcsp will break on SMP boxes and I'll have to go to a real
sound card when this machine gets a second CPU.

Anyway I just was able to find the 2.2 patches. Applied them to 2.2.15,
but it failed on one hunk in joystick.c, but since I don't have a
joystick, I'm gonna go ahead and try to compile it. Will take a look with
the 2.2.13 kernel what's changed since then, seems some SMP-related
spinlock stuff got changed...
