some don't. Open a terminal and try this, enter 'sudo amixer cset numid=3 N'
where N is a number and N can take the values 0=auto 1=analog 2=hdmi. You
can use this to force sound to a particular output.
So 'sudo amixer cset numid=3 2' should send all sounds to HDMI.
Thank you, this command solved the problem I was having with no sound in Scratch. Is there any way to set this to be the default so that it is set every time I power up or reboot the Pi?
