Acer 5920g audio over HDMI

[theBuh]

Hi all.
I have Acer Asprire 5920g laptop running Intrepid.
I trying to get audio over HDMI working. But im failed to do so.
Im upgraded ALSA to latest version (1.0.19).
Even installed Realtek Linux Audiopack 5.11 (wich is almost same Alsa 1.0.19)

Heres output of lspci:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

Its detected by Alsa (aplay -l) as

card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC1200 Digital [ALC1200 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I have sound over S/Pdif Toslink connector, buildin speakers, AC3 passtrough and everything.
But not HDMI audio.
I think there should be device in list of aplay -L something like

hdmi:CARD=Intel,DEV=0
    HDA Intel
    HDMI Audio Output

But theres none.

In Jaunty Alpha 5 (even with pulseaudio 0.9.15 pre release) situation is the same.

Nvidia drivers version is 180.22.

Its not hardware problem since in Windows HDMI audio working perfectly.

Any ideas?

bump?

[smith912]

I have the same problem. Alsa and Nvidia driveres are the same.

Anybody a idea?

Hi,

after several hours i finally managed to get my hdmi sound working with my acer 5920g.

my problem and perhaps yours too was that i didn't upgrade alsa-utils to 1.9 which made it finally working.

Here are the steps that brought my tv screaming:
- update alsa-base to 1.9
- update alsa-utils to 1.9
- stop your XServer, run "alsaconf", reboot

I'm not sure if alsa-base 1.9 works, due i'm using an snapshot from 12. April but certainly worth a try.

some system info:

Hopefully this helps for getting your tv receiving the sound signal

el_capone, could you please post output of "aplay -L" too?.

Hm could it be yours .29 kernel that makes the difference?
Since i installed latest snapshot of alsa driver and utils

cat /proc/asound/version 
Advanced Linux Sound Architecture Driver Version 1.0.19.46.g516fa.506.gb750c.
Compiled on Apr 16 2009 for kernel 2.6.28-11-generic (SMP).

And still no sound over hdmi =\

[theBuh]

Well i upgraded my kernel to 2.6.29.1 and recompiled alsa driver and utils, and theres still silence.

But! I saw a first glimpse of light at the end of the tunnel.
When i tried hda-analyze tool from alsa (after a little patching) i got some results - my sound card codec audio out for hdmi (in my case node 0x10) wasnt enabled.
After i enabled it - i finnaly got pcm stereo signal icon on my reciver.
But still cant play any sound. speaker-test -Dplug:iec985 -c6 -twav doesnt work etc.

I think i got really close to solution But not there yet.

Any ideas about how to route iec985 sound signal to that audio out node (0x10). I suppose atm my default node is 0x06 - which is front toslink connector.

Hi
Did you enable digital audio?
Open gnome volume applet - settings/preferences button - and select the suspected devices. When done, I get a new tab in the volume manager with switches. Including IEC958 in my case.
Could that be the case here too?

[theBuh]

Yeah ofc. Both IEC985 and IE985 Default pcm. Tho i dont know whats latter doing. It seems not affecting anything.
And anyway toslink connector working ok.
