Trouble getting audio to work with HDMI Radeon HD 8550G and ALSA

Disco Dave · 2015-05-01 23:44:04

I am using the proprietary driver for Radeon HD 8550G. The HDMI is able to display the visuals just fine on my tv, however the audio isn't working. The audio instead always plays through my laptop speakers. Here our my relevant files,
