Initially figured this to be in only games, but in i.e. YouTube all the same. Fresh start, sound via AMD HD Audio Device on HDMI port towards Sony 4K-TV sounds good. After hibernation however, sound is scrambled (like being to far away from an antenna in analogue radio). I bought a new HDMI cable to ensure that wasn't the culprit.
Seen this behavior at least in Adrenalin 19.7.1 through 19.8.1.
