Porting ALSA drivers to OSS may be easy, according to OSS ;)

Well, I looked here:

Instead of here:

I haven't tried FreeBSD for a long time (before SB Live! was supported) 
but I knew my SB Live! is supported for some time now.

I also have read comments from others about sound support on FreeBSD, and 
when I compared the supported cards on the pcm man page with the 
commercial OSS and ALSA supported cards I felt they were right.

But I'm much happier now that I know I've searched the wrong places and 
FreeBSD supports much more soundcards that I could have imagined.

I can't remember which is the soundcard in the old Compaq Presario laptop 
my wife has.

But my desktop will migrate in a few days. Thanks for the quick answer :)


BTW, you're right about the drivers, I haven't understood it the first 
time (OSS API != OSS drivers).
