Greets. On my new PC, there's a cmipci chip built-in to the mainboard. It's noisy, but that's as expected.
But there's a weird issue with it. I can play 16bit stereo 44.1khz sound just fine. 22 khz, though, is inaudible. In fact, everything but 44khz stereo 16bit gives me either white noise or inaudibility. Facts about the board: The sound part has three jacks... which can be configured as 6-channel output, or output/mic/line_in. No SPDIF, no joystick/midi port, no FM part. Board: Asus A7M266-D ALSA version: 0.9.0beta11 Hope this gives someone an idea what to look for?

And then a couple of feet more, just to be sure. _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
