I bought my EMU-0202 at the beginning of 2009, but it only worked at 44.1KHz. Now we've got it working at up to 96Khz in Linux, with an Alsa change forthcoming.

Here's the story: Shortly thereafter Creative released Mac USB drivers and I spent some time looking at the source and saw there were two ways to set the sampling rate: a "direct" method and a "clock" method. The "Extension Unit" code confused me, and I never got around to mapping between the Mac USB and the Linux USB stacks.

But just recently "mellowman" described a patch to get 48Khz sampling working. Over at UbuntuForums "v.stiff" reported success, and I then figured out the quirk to extend it to the full range. CannibalZerg either took my patch or figured it out alone, and we've all tested it and it works!

So I have got the EMU-0202 working at up to 96KHz on Linux. Others report the 192Khz sampling working on the EMU-0404, but the 0202 says you have to disable the input monitor before doing that, and it's not clear to me that that's working yet.

Why's this useful? Well, it lets me use my Quisk K3 LPPan package to see 96Khz of the band instead of 44KHz, a major improvement.
