Hi Joel,
this is more informed guess work, so take it with a pinch of salt, but it
maybe worth the effort.
First try to create a plug device for your HDMI:
pcm.my_hdmi {
type plug
salve { plughw:CARD=PCH,DEV=3 }
}
Now create your !default with dmix:
pcm.!default {
type dmix
slave { my_hdmi }
}
Perhaps you can even shorten it to putting the
plughw:CARD=PCH,DEV=3
inside the default dmix device.
I know that getting all this to work with Firefox and GUI can be cumbersome.
Perhaps pulse might be in the way, but I know much less about Pulse than ALSA.
Still the plughw, which converts samplerates may help.
Best wishes,
Jeanette
