Rene, Just wanted to let you know that if you still haven't gotten sound working with the Tangent 8000S (we haven't), you should look into its counterpart. The Tangent 8000S is really the MSI Crystal 945 barebones unit, with parts installed and optionally Windows installed. MSI has a newer unit with identical case and external connections - the Crystal A410 . It uses an ATI chipset, but still an ALC262 codec. We got one in today and audio "just worked" for us! I suspect that the BIOS on the Crystal A410 is giving ALSA the info it needs when it auto-probes the BIOS, unlike the BIOS on the Crystal 945 (Tangent 8000S). So, you might want to check it out. Unfortunately for us, we already have several of the Crystal 945's deployed to customers, so we still need to try and resolve the audio issue with those units.
