I have an old Compaq tower with AC97 integrated audio running Ubuntu 10.04. Got DSD installed & running, but having trouble decoding audio from both the discriminator tap on the scanner and from unfiltered TRBO audio samples on the computer. It decodes, but is EXTREMELY distorted. We were able to pick up maybe one or two words just very faintly, but not much. Would finding drivers for the soundcard help? Tower is a Compaq SR1012NX tower, for the record. Thanks.
