Linux SOLVED No passthrough sound HDMI ATI

Ive been pulling my hair out for days tring to get this to work. I must have read every HDMI thread on here and none have fixed my sound issues. I've tried 2 fresh installed nothing seems to fix it...... Anyway:

I have sound in XBMC but only stereo. I currently have output set to ALSA (Defaults), and whatever I try doesn't seem to work.

aplay- L

aplay -l

So I have tried as output & passthrough in XBMC:
hdmi:CARD=Generic,DEV=0
alsa:hdmi:CARD=Generic,DEV=0 (this worked on my previous ubuntu)
hdmi
plughw:0,3
etc etc

my asound.conf is currently empty or non existant.

The wierd thing is in Ubuntu if i try:
I can hear front,left, front-centre and front-right. The 2 rear channels are very faint and seem to be coming out of the front speakers, definately not the rear ones)

if I try
I can only hear the front-left and front-right

I have tried editing /etc/pulse/daemon.conf and changing:
; default-sample-channels = 2
; default-channel-map = front-left,front-right
to this
; default-sample-channels = 6
; default-channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe

Please can anyone help, hardware & software: A6-3500, A75m-ITX, Ubuntu 12.04, Catalyst Control Centre 2.14

Is there an "hdmi (ALSA)" entry in XBMC? Try that one first if it exists.

There is and after selecting this there is no sound. Even after a restart.

I can get stereo sound from "Defaults (ALSA)" as the output
But once I try a DTS or 5.1 or AC3 stream I have failed to initialize audio device - this is with "hdmi(ALSA)" as passthrough device

Edit: Yes I have AC3 capable and DTS capable receiver selected

I don't think your "aplay -L" output should list the card as "Generic" (the cards I have always list the manufacturer: NVidia, Intel, Creative...) . Did you install the drivers for your ATI card?

I have the properietry drivers installed from the system settings > additioanl hardware

Catalyst Control Centre 2.14

Is there another way to install the drivers?

The outputs of aplay do look ok. My ATI system works with

hdmi:Generic for pass through.
Defaults (ALSA) as audio output

asound.conf
pcm.!default plug:hdmi:Generic

Hi, I have a very similar set of issues (and have tried most of the same things) as Charlie0440. I was recomended to post in an ATI specif room. The advice I was given was that i did not ahve the ATI drivers. My aplay -l looks like this

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH],device 1: ALC892 Digital [ALC892 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Generic [HD Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0

Have tried plughw:2,3 in custom setting but no joy.

So my two questions are:
1) How does one install audio drivers on a live install (ie I'm running xbmc off a USB drive as an installed program)
2)How can I FTP into the XBMC to look at the files like text files I creat with the aplay-L?

Oh BTW I'm running ASRock H67M-ITX, 4GB Ram, A Radeon 6450 Graphics card Intel i3 2100 processor with Eden 11.0 I have HDMI connected to the graphics card and an optical Toshlink out for sound. Analog sound works fine using the generic driver. HDMI video works fine. The digital audio outputs give me nothing.

Any help you can give will be greatly appreciated. i have been trying to get this to work off an on for 4 weeks

hdmi:Generic didn't work as passthrough

Im starting to think its a Ubuntu problem, how can I install the ATI drivers? Is the proprietry drivers not all that is needed?

Ok some more results. If I open up a 5.1 movie with ubuntu movie player my amp shows LINEAR 44khz
Same movie opened in VLC shows LINEAR 48khz

Output device in VLC is HD-Augio-Generic, HDMI 0 HDMI Audio Output

Sure my amp used to say "3/2.1"

Please post a debug log, I want to check for the message when XBMC tries to open hdmi:Generic.

EDIT: you have configured pulse audio as default. In this case alsa pass through does not work because pa already uses the device.
