[mythtv-users] No sound via HDMI on my Yamaha RX-V465 A/V receiver

[Jason McKnight]

Check in alsamixer (command line) to see if the Audio device is enabled for HDMI. You probably have multiple IEC958 (or something like that... at work today so I can't look on mine). Enable them all.

Hi, 

I have a Yamaha RX-V465 A/V receiver connected to my TV via HDMI. The Yamaha does have a HDMI repeater for splitting up audio and video. 
When I connect my MythDora 10 box directly to the TV via HDMI there's video and sound. So my setup seems to be ok. 
But as soon as I connect my MythDora box to the A/V receiver via HDMI I do not get any sound towards the receiver. The receiver tells me that there's no audio input signal. But video is working fine then. 

mplayer -ao alsa:device=hdmi putsomemp3here runs fine without errors. But without any sound. 

Yamaha support says this might be a hardware related issue and I should apply the latest firmware for my HDMI equipment. 
It's not a hardware related issue because when I boot windows on this box, I have video and sound via HDMI to my Yamaha. 

It's an ASUS M3N78-VM with the latest NVIDIA drivers (185 I think) from the NVIDIA page. 
Kernel is: 2.6.27.9-159.fc10.x86_64 
I can not upgrade to the latest kernel because HDMI audio is not working then. 

Thanks for any help. 
Bjoern
