please create asound.conf file with following content:

Code: Select all

defaults.pcm.card 1
defaults.pcm.device 3
defaults.ctl.card 1

and copy it to /etc every time you want to have the sound redirected to HDMI.
if you want to get back to original configuration then you need to delete /etc/asound.conf and restart applications which uses sound card.

I tried before /~.asoundrc with this information, and now /etc/asound.conf.
If I test with speaker-test command, not show any error, but no sound.

I tried copy2ram with rootcopy /etc/asound.conf, without my modules and no sound yet.

alsmo - make sure HDMI is not muted.

I have read a lot about this problem, many drop out, others get success, but for me no effect.

Very strange, I can test the HDMI device, I see the volume control on the alsamixer.
I'll keep trying.

Thank you
