Title: A20 sound while having a display on HDMI
Post by: otyugh on June 14, 2014, 02:42:52 AM
Hey,
I can't seem to be able to get any sound from the jack output while a display is connected by HDMI.
But. When I play a sound that way, HDMI image drop, I get a message (from the screen) telling "frequence unsuported".

I guess it's because sound tries to use the HDMI. I guess there is some parameters to change in script.bin. But which ?

Any clue ? Am I on the good way ? Thanks for any answer.

solution is here
the default output is hdmi sound
change it to headphones out by editing /etc/asound.rc as explained here
