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. [..]"
