Hi,

# sysctl hw.snd.version
hw.snd.version: 2007061600/i386

Yes I know that. For example, TS needs to open the device in full duplex
mode, because it needs record and playback but Enemy Territory only needs
playback but still it opens in full duplex.

Well, 2 sound card time is over now. I've configured TS and ET to work with
the best possible sound quality and I must say that the sound definition is
very good, no parasite noises. It's basicly working great.

But just for me to get the right idea. The sysctl variables that define the
virtual channels don't matter anymore? Because whatever values I use for
this variables it'll always work fine.

Another freebsd gamer friend is running -CURRENT (from 2 weeks ago) and
reported no problem. He didn't need to do anything because it seems that the
changes that makes this possible are already commited to HEAD.

Thanks once again.
Cheers
