Hi,<br><div class="gmail_quote"><div><br></div><div>I'm resending this mail as I have previously sent it from an unregistered address and I'm not sure it got through, so apologies if this appears as a duplicate.</div>
<div><br></div><div>I have an Asus Nvidia GeForce 210 graphics card and am using the HDMI cable connected to my TV ( which itself 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. My other TV inputs work find with surround sound as far as I am able to determine.</div>
<div><br></div><div>Any ideas?</div><div><br></div><div>Here's the output of aplay -L:</div><div><br></div><div>$ aplay -L</div><div>null</div><div> Discard all samples (playback) or generate zero samples (capture)</div>
