I have a Dell Latitude D630 and Windows 8. The generic Windows sound driver made the sound for the laptop run, but not with the docking station. I installed the Sigmatel drivers for Windows Vista 32bit. They also worked for me on Windows 7. First, they didn't wanna install, but then I made a BIOS update from Revision A03 to A18 and it solved the problem. Now again I have sound for the laptop, but when connected to the docking station the following happens: When I set the normal speakers as output: Sound starts to play through the speakers connected to the docking station, but aborts quickly (for example the Windows sound when changing the volume). When I set the SPDIF out as output: No sound at all! The Sigmatel website obviously doesn't provide drivers since it's not existant anymore. The audio business was sold to IDT, but the IDT Website sucks: Detailed descriptions of all sound cards, but no drivers at all! There was an IDT modded drivers section on laptopvideo2go.com before, but unfortunately the project is dead. I can't even find the uploaded files anymore. Anyway, one doesn't know if it works for Win 8 at all. Audio device: STAC9205 Device-ID: HDAUDIO\FUNC_01&VEN_8384&DEV_76A0&SUBSYS_102801F9&REV_1002\4&C38AAC3&0&0001 I tried the following drivers from the Dell website already which according to Windows 8 work, but give me the described sound problem: - 2Y0VM - R153997 - R171788 - R171789 - R218148 Any ideas how I can get this to work? Any other IDT drivers available?
