I have two different sound devices for output:
"Internal Audio Analog Stereo" for headphones
"High Definition Audio Controller Digital Stereo (HDMI)" for speakers
For example: if I open a music player and start a song, it plays out fine from speakers. But when I try to control volume it controls "Internal Audio Analog Stereo" instead of HDMI. I have to manually select the proper output from Gnome sound applet or whatever that thing is called.
How can I set HDMI as default sound output?
