The ALSA part that is.
I now can successfully do:

speaker-test -c2 -D hdmi:CARD=HDMI -twav -l2

or

speaker-test -c2 -D hw:1,3 -twav -l2


But when I use either hw:1,3 or hdmi:CARD=HDMI in mythfrontend's setup,
I get errors about the devicename (hw:1,3) or no sound at all
(hdmi:CARD=HDMI).
So what should I enther for sound in setup for mythtv to use HDMI sound
only?

Kind regards,
Udo
