[mythtv-users] No HDMI audio

["José Tomás @ Chico"]

Hi!

I have this issue almost a year, I'm living with it, but I want do get 
rid of...
First I did thought that I didn't have sound on HDMI channel for some hw 
reason, since a colleague have it fine at first time when did install 
mythtv.

I tried some suggestions by updating asound.conf, nevertheless I had no 
success.

After some investigation I did found that my colleague did the 
installation having only hdmi connected, when I used VGA plus common 
jack out.

So, in my case system is giving sound through the preferred out channel, 
I have to select on mythtv if I want to have on different out, when I 
need SPDIF simultaneous to HDMI and or with regular jack.
Do anyone knows about examples for having sound on both channels through 
asound.conf editing?

Thanks all!
