Public bug reported:
I have an Nvidia based video card that has an HDMI output + a DisplayPort
output.
DisplayPort output audio is listed as "Digital Stereo (HDMI)" and HDMI output
is listed as "Digital Stereo (HDMI 2)".
I prefer to use "Digital Stereo (HDMI 2)".
But after each display sleep (screen lock for example) audio is switched to
built in audio
