Looks like I've been praising the snd_envy24 driver too much last week. Today I've noticed a very strange problem. Compared to the opensound.com (and winxp) drivers, the fbsd drivers sound less bright. I've recorded the output of the soundcard with another soundcard -- and could easily identify (using ABX) the source recorded using the fbsd driver. In audacity, frequency analysis showed that high frequencies were cut of early compared to the other drivers. So the difference is really there. My guess was that ENVY24_MT_RATE might be set to a wrong (too low) value, but it seems to be correctly set to 44100Hz (I've used a standard 44100Hz/16Bit flac file for that test). Any other ideas what could be causing this? If someone could give me a hint, I'd have some time to investigate this. But I'm really puzzled right now. This is with envy24 driver on 6.2-RELEASE with Audiophile 2496. Thanks, Stefan
