Hi,
I check that option on audioctl and it was ok. And remember: on
OpenBSD 4.1 sounds good (only xmms is going faster...).
The other problem (the bigger) it was the incredible low speed to
access the hard disk. Right now, like i said before, i am using 4.1 but
the output of the 4.2 it was the same:

So, why in 4.2 is more slow? In fact, only for testing, I did this:
1) install 4.1 (no compile kernel, no nothing.....only the install from
the CDs)
Result: The HD was ok and fast (How do i know? Because it was faster
unpacking ports.tar.gz)
2) Upgrade to 4.2 from the CDs:
Result: The HD i/o access....sucks; 15+ minutes to unpack ports.tar.gz.
(Pretty simple the upgrade process from CDs btw).
Regards,
Alvaro
