I've had WMC up and running for about a year now, no problems. Tonight we decided to watch a movie that I have as an *.mkv file - we do this all the time, at least once a week if not more. I shut down WMC and played the movie in VLC Media player. When I went to start WMC again, the sound was gone.
The sound works in the rest of the system. I can hear computer sounds, and VLC and other media players work fine. It's just WMC that has no sound.
I checked all my devices and drivers, no errors. Though to be honest, if that was the problem I'd expect all sounds to be gone.
I removed WMC from the system by using the "Remove Windows Features" in Control Panel, and then re-installed it. No difference.
I did notice however that removing and re-installing WMC, I didn't have to re-setup all my channels, etc. The settings "stuck". (Oh, by the way, I did re-run the sound setup in WMC, no difference).
I'm wondering if maybe my WMC settings are corrupted somehow? Is there some sort of config file perhaps?
Any ideas? I have no backup plan here, this is my only way to watch TV. I guess I could wipe the drive and start from scratch, but I'd prefer not to. (And I'm worried what happens if that doesn't fix it).
