Hi all.
When I plug my HDMI cable to my TV, I have the image but no sound. I read somewhere on this forum that this may be caused by the fact that my s/pdif channels are muted. I have been to alsamixer and there is no way to unmute s/pdif.
Can you help ? Thanks in advence.
I provide you some basic info :
