I would to ask about the issue to be found under Linux - is it valid for
OpenBSD's "audio" too?

"The latest versions of ALSA which are included with Ubuntu Edgy, and I
think Dapper Drake as well, will resample all audio to 48kHz if your
soundcard does not support hardware mixing. This is also true if the driver
doesn't support hardware mixing. As far as I can tell, there is absolutely
no support for hardware mixing with any of the Envy24 chips in Linux. The
problem with this resampling is that by default ALSA uses a poor resampling
algorithm to save CPU usage, and destroys the quality of everything played
back. ALSA uses this software mixing and resampling in order to let more
than one application play audio at the same time. I have found a solution to
the audio quality issue however. [..]"
