Hey there, I have the same card (Audigy LS) sitting around here somewhere, I used to use it for DJing/Mixxx and hated it so utterly I layed out $150 on an M-Audio Delta 1010. :)
The CA106 driver is a binary blob from Creative that doesn't support many features correctly and is generally pretty shoddy. Creative sucks in open-source, and even their closed-source Windows drivers are buggy, terribly written, slow, and they don't support them so that you'll buy their latest card to stop the bugs. My old Soundblaster 5.1 Platinum had a bug in the final driver version that would leave EAX effects running after they were activated (the driver's EAX cleanup was bugged) - Creative will never fix it, but that's cool because I don't use it any more, and I'm never buying another Creative card. The LS won't work in duplex mode in JACK unless you try something no one else has (CA106 driver flaw), and the latency is high (though that's true of any consumer card). The pops and crackles you're getting with ALSA are probably a problem with your Mixxx latency slider or your frequencies between Mixxx/alsamixer. Don't quote me on this but I think I ran the LS at 44100 because I was totally unable to get 48k to work properly. The card theoretically supports 96k but from what I understand it pretty much just downsamples everything to 44100/48k anyway. I liked the LS because I paid $30, and it made sound and it sounded a world better than my onboard. It's not a bad card until you try to do anything that isn't straight-up one-stereo-out playing stuff. Don't bother with a real-time kernel. Real-time processing is not really what it sounds like - its more to do with guaranteeing a 'done-by' time than super-low-latency - and while it will be lower latency and a touch faster than a stock kernel, the extra bother (especially for a budget consumer card like the LS) will just break your spirit. Try the low-latency kernel distributed with Ubuntu Studio or one of the Gentoo low-latency patchsets if you want to push the LS as far as it will go. Or do yourself a huge favour and buy an M-Audio card or a Maya. :) ~Yorick ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
