Enable audio through HDMI on GT240

Does anyone knows when alsa 1.0.23 backport will be available for ubuntu 10.04

EDIT: one of those nasty tricks Denon plays... things you don't even know to look for before you buy. But since nvidia didn't have HDMI audio until just recently, it didn't matter. Mobo has digital out.

So you have to run audio cables with every device you use an HDMI cable with? That doesn't sound right. If I were you I would set up alsa to send LPCM for multichannel audio. I can't imagine that wouldn't work.

The Ubuntu mailing list or emailing the maintainers directly is a better place to ask that kind of question.

Straying way off topic, but yes, there were several Denon AVRs with HDMI that would "repeat" the HDMI audio downstream (ie. to the TV), but could not decode it at the AVR from HDMI. Again, wasn't much of an issue for me until now, when I finally can get HDMI audio from my GT240, previously I only had DVI ports, so that was always a 2-cable solution. Now I don't have to worry about buying a mobo with digital audio.

Surprised your receiver doesn't support LPCM but ok. Also, you can do audio over DVI. That's why you see video cards with DVI ports that have SPDIF IN connectors.

we're still back to the same problem... AVR *does not* decode hdmi (nor any kind of DVI) audio... really guys, I can point you to the PDF spec sheets).

Again, AVR not decoding is a non-issue.. it was time for an AVR upgrade, it is on order, and when it arrives, I can go from 4 cables (1 HDMI+digital audio each to HTPC and DVR) down to 2 (this model also has HDMI pass-thru so I won't have to turn on the AVR just to use HTPC for surfing). Once it arrives I can verify if the HDMI audio is working. For now I can only say that "aplay -l" suggests that it does, which is a step further than I had been before.

Am curious which receiver you own..?

Denon AVR-689 : http://www.usa.denon.com/ProductDetails/4230.asp

The document you want is the HDMI Specifications Guide .. which curiously is missing from the 689 page, but is linked from the 589 page: http://www.usa.denon.com/AVR_3_Digit..._x89_v0708.pdf

The 589 and 689 do not decode any HDMI audio, only repeat it on HDMI-out.

Denon excels at excluding features you'd never think to check to see if missing. Be amazing to see how product marketing managed to convince engineering this was an acceptable feature compromise.

New AVR is here... HDMI audio working from DVR... trying to get HDMI audio from my nvidia card.

Ubuntu 10.04. I finally got speaker-test to work with

>speaker-test -c6 -twav -Dplughw:1,7

trying to figure out how to translate that into an .asoundrc file??

(I can play movies in smplayer b/c it has an audio setting)

EDIT: This

pcm.!default {
type hw
card 1
device 7
}

gets me sound from Flash inside Firefox.. but I don't have any system sounds from Ubuntu yet...

EDIT2:
working: speaker-test, smplayer, Flash via Firefox
not working: xbmc, Songbird, Rhythmbox, system sounds

PulseAudio settings?

I've set HDMI as the output in both the System Sound panel, and in the Pulseaudio sound settings.

No change in the Works/not-works list

EDIT: I didn't realize that was a link at first.. will try and report back..

EDIT2: Still no joy after editing the pulse file.

(In case you couldn't tell, I'm down to the shotgun approach here.)

I did have a problem last night with an incorrect ~/.asoundrc which conflicted with the (correct) settings in /etc/asound.conf, preventing snes9x-gtk from outputting audio. I'm using the simple two-line asound.conf on the linked wiki page which sets the default and iec958 devices to the HDMI output of the NVidia card.
