I just went through something similar when changing the video card on my
MythTV machine. I used aplay -l to get my list of devices. MythTV has
a sound setting, and I also configured /etc/asound.conf so that mplayer
and rhythmbox would output sound through HDMI.
Here is my /etc/asound.conf:
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type hw
card 1
device 7
}
ctl.!default {
type hw
card 1
device 7
}
You should probably check to see if XBMC has its own sound settings that
need to be tweaked in addition to asound.conf. Also keep in mind that
there may be a per-user setting in $HOME/.asoundrc
