The link above doesn't provide any useful information on the problem and it contains itself a non working link... Can somebody explains exactly what's going on ? That shouldn't be hard to fix. I can't believe the problem has been around for 2 years and nobody actually bothered fixing it properly. Send me a sound card that needs that hack and I can take care of it myself.
