[mythtv-users] Issues with audio over HDMI

[Phil Wild]

Hello all,

I am chasing some expert advice...

I am building my first MythTV frontend. I have an Asus m3n78-em motherboard
with onboard HDMI. I have install mythbuntu amd64. I have upgraded alsa to
1.0.18.

I can send audio to the TV through hdmi using aplay

e.g. aplay /usr/share/sounds/card_shuffle.wav

aplay -l lists

root at juliette:~# aplay -l

and I have setup a default entry in /etc/asound.conf as

pcm.!default {
        type hw
        card 0
        device 3
}
