I am using ma78gm-s2h mainboard and gtx260, there is no sound on ubuntu. There is a spdif connection from my videocard to mainboard. And it connected with hdmi to my tv. It works fine with windows but not with ubuntu. Is there any way to fix this? I tried everything like troubleshooting, nvidia driver, alc889 driver etc.
Edit: there is only analog and digital choices exist at settings
