Hi,
I got audio over HDMI working just fine using the following:
Mainboard with onboard Graphics Card that can du vdpau: P5N7A-VM
I'm using mythbuntu
what I needed to do is create the file /etc/asound.conf
pcm.hdmi_hw {
type hw
card 0 # <----- Put your card number here
device 3 # <----- Put your device number here
}
pcm.hdmi_formatted {
type plug
slave {
pcm hdmi_hw
rate 48000
channels 2
}
}
pcm.hdmi_complete {
type softvol
slave.pcm hdmi_formatted
control.name hdmi_volume
control.card 0
}
pcm.!default hdmi_complete
use the 0 and 3 I found out by running aplay -l which lists
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC1200 Analog [ALC1200 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC1200 Digital [ALC1200 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]
Subdevices: 1/1
Subdevice #0: subdevice #0
After this I used alsamixer to unmute the device (basically just try to
unmute everything until you here something)

Patrick
