Hi,

please connect to the HDMI device and post the output of

  aplay -l

It should be possible to select the HDMI device when starting a user
session by ~/.asoundrc =C2=B9. In my case it does look that strange, since
I've got an unusual alsa-base.conf . However, depending on the
computer's audio device the number of the "ALSA device" might change.

I can't comment on this. I would expect something like this, when using
a CRT in combination with a wrong xorg "Modeline".

Regards,
Ralf

=C2=B9 This is on Arch Linux, but   aplay -l   and   .asoundrc   should wor=
k
with almost all, if not all distros as well. You can ignore
/etc/modprobe.d/alsa-base.conf , I only wanted to show, why aplay
mentions card 0 and card 3, but no card 1 and card 2. Those are
placeholders for backwards compatibility with scripts I used with
another machine.
