Hi,
I have an Asus Nvidia GeForce 210 graphics card and am using the HDMI
cable connected to my TV ( which connects to the surround sound unit ).
I've only managed to get this to work with the stereo output. If I use any
of the 5.1 options it's just silent ( although the signal monitor in paman
goes crazy as though it should be making noise ). Also when I use
speaker-test -c 6 on two of the outputs it goes through all 6 speakers and
seems to be working, but it is silent.
Any ideas?
Here's the output of aplay -L:
