HDMI audio doesn't work

Vijfh · 2013-07-05 11:42:01

I'm using an Acer Aspire Revo R1600 as a mediacenter using XBMC. It's connected to our Samsung TV (pretty sure it's the ES8000) through a Pioneer VSX-922 amplifier (or to be more precise, A/V receiver). It's connected to the receiver over HDMI, which links the video through to the television.

Now the problem: This setup worked fine with my old TV, a pretty old Philips model. The second I plugged in the new TV, the amplifier wouldn't output any sound anymore. When I connect it to my computer monitor (which has a 3.5mm jack to connect PC speakers to) sound works fine, and so does the 3.5mm headphone jack on the front. I'd like not to use that though, seeing that the output volume is extremely low and I don't like cranking up my amplifier about halfway just to watch a movie at reasonable volume.

Here's an lspci:

And arecord -l:

Somebody please help me, I'm clueless.

--EDIT-- Here's a screenshot of AlsaMixer (I'm SSHing into the machine from my desktop computer)

Okay, I tried connecting a Windows laptop to the amplifier over HDMI, which worked just fine. The amplifier showed which channels the laptop was outputting, and I could hear the sound just fine. When I try to output sound via the HTPC though, the channels don't appear on the screen and I can't hear anything.

speaker-test -c 4 (I have that many speakers) doesn't work either.

You have several muted channels in you alsamixer output (the MM at the bottom). Have you tried unmuting the speaker and headphone channels?

Vijfh · 2013-07-06 17:38:55

Nope, that wasn't it, sadly. Also, shouldn't HDMI go over S/PDIF?

2ManyDogs · 2013-07-06 17:52:50

Yes, you're right. It looks like that channel is disabled in your mixer output.

What do you get for

aplay -l

(not arecord, aplay)

Does this help at all: https://wiki.archlinux.org/index.php/Ad … s_not_work

[root@xbmc ~]# aplay -l
**** List of PLAYBACK Hardware Devices ****

I tried following that guide, but

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

didn't play anything. I also tried connecting the computer to the television directly, still no audio output.
Something I also tried was putting the aplay -D in a while loop, and then plugging the HDMI cable in while it's looping, to no avail.

Did you try making a .asoundrc file, and specifying device 3 as your default device?

(edit) -- never mind, I see you're only supposed to do that if the previous command works. Sorry, that's all I have, except for maybe looking up the device and making sure the correct modules are loaded. Your device is recognized, so there should be some way to make it work.

I just found this: https://bugs.archlinux.org/task/33988 - Might be related?
I'll try kernel version 3.10 from the testing repo tomorrow, or I could try grabbing a 3.7.x from somewhere.
