Intel HDMI audio - No audio in X, works in console

[Bill Wittig]

Hi,

I've got a G45 MB (Gigabyte EG45M-D2SH)

I've installed the 2.5.99.2 xf86-video-intel driver
the Realtek v5.09 ALSA modules which includes the ALSA v18a  
patch_intelhdmi code

aplay -l shows the Intel HDMI device:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC883 Analog [ALC883 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC883 Digital [ALC883 Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: INTEL HDMI [INTEL HDMI]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

I'm using MythTV, audio output device set to ALSA:hw:0,3 (using 0,0  
works as expected for
analog out)

When MythTV is displayed (i.e. X is running), no sound is heard. If I  
switch to a console
(Ctl-Alt-F1) the audio is working fine.

Any ideas?

TIA!
