I can't get any sound over HDMI from my ION2 based system. I have the
sound drivers compiled into the kernel. Everything seem ok, but I get
no sound other than through the analog Intel device (front jack).
Here's some output from lspci
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
Subsystem: ZOTAC International (MCO) Ltd. Device a140
Kernel driver in use: HDA Intel
03:00.0 VGA compatible controller: nVidia Corporation GT218 [ION] (rev a2)
Subsystem: PC Partner Limited Device 3100
Kernel driver in use: nvidia
Kernel modules: nvidia
03:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
Subsystem: PC Partner Limited Device 3100
Kernel driver in use: HDA Intel
This is a git compiled kernel on a Gentoo system:
# uname -vspor

I can see the devices using either aplay -L or by looking at proc.
# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.22.1.

Using any of:

aplay -D hw:1,7 test.wav
aplay -D hw:1,8 test.wav
aplay -D hw:1,9 test.wav
aplay -D hdmi:CARD=NVidia test.wav
does not result in any sound on my TV (where I have verified that
other HDMI devices can play audio on the same HDMI port). "aplay -D
hw:0,0 test.wav" will play audio fine through the front analog jack.
Any ideas?
Thanks
