I'm running Blender 2.76 on Mint Linux. Normally when I output sound from a newly installed application, I am used to going into PulseAudio Control and selecting the correct audio device. I am using Nvidia HMDI audio. See the screenshot. I have the option of selecting the correct audio device but when I click it, nothing happens.
I'm relatively new to Linux (1 month) and very excited to use Blender as a video editor, this issue is holding me back.
Any help would be greatly appreciated.
