Ok, works as before.

It didn't want to do it for quite a while - I eventually got to repeat
it... There are a lot of artifacts in the sound that are not there when
oss is active - may leave that for another day...
The attached patch I got from Jaroslav some time ago when he was trying to
chase the same bug - it was still applied.
The other diff is the differences in the ymfpci output. The lspci output
is identical over before (alsa), oss, after (alsa) - not supplied.
I still have all the original files if required.
