Hi LAU, This is my first posting here. Hope to do lots more... I have a M-Audio Delta 1010LT multitrack sound card in my computer and am having lots of trouble with it. I'm running Linux 2.4 (Fedora Core 1) with the "Planet CCRMA" audio environment on a Pentium 4 PC. I use Audacity 1.2.3 for recording, etc. Everything worked fine with the built-in (stereo) sound on my motherboard. I installed the 1010LT and rebooted. The computer found the card and seemed to be happy with it. But many things seem to be wrong. I'm using envy24control to get the mixer, patchbay, sliders, etc. My main (first) question is how to get more than 2 channels recording at the same time? When I pick 4 channels in Audacity, it does indeed record 4 tracks but the second two are copies of the first 2. The little drop-down menu in Audacity for selecting the source (line-in, mic, etc) is empty and the input and output sliders seem to have no effect. Any helpful tips or pointers would sure be appreciated. I'm very new to Linux so you might need to t-a-l-k r--e--a--l s--l--o--w--l--y 8^) Thanks in advance, Mike Jewell
