  • Linux Lite: 4.6 64bit
Hello All

I have an annoying problem with an ancient Asus A8N32 motherboard. I have installed Linux Lite 4.6 - 64 bit without any issues other than the sound from the onboard coax digital output doesnít work at all. It works from the onboard analogue output and also from the HDMI output on the Graphics card. Because of the speaker configuration I have it would be very handy to get the coax port working. In Windows 10 the output works fine so I know it isnít a hardware problem.

When I open the audio mixer app I can select Digital Stereo (IEC958) output but no sound comes out. In the Output Devices section the Port is described as Digital Output (S/PDIF). Selecting Analogue works just fine.

Iíve tried several Linux distributions (Mint, Fedora) and they donít work either so I guess this problem may not be solvable. Iím not sure what info might be helpful but I can provide the followingÖ..

The System Summary app describes the Audio Adapter as Nvidia CK804
