This used to be possible by using: amixer cset numid=3 2 for HDMI0 amixer cset numid=3 3 for HDMI1 amixer cset numid=3 1 for 3.5mm headphone jack However, now trying to set this gets the following error: amixer: Cannot find the given element from control default It seems that by default, it will now use the hdmi output for whichever one is connected, and will only output through the headphones if no hdmi device is connected.
