No 8 channel audio on July update

Set Audio settings to “default”

Both players disabled. Sound OK
Both players enabled. No sound
MMAL only enabled: Sound ok
OMXPlayer only enabled: No sound

I enabled both because the default values (both disabled) cause shutters in my mkv files. OMXplayer play fine and MMAL plays with a little less shutter then both disabled.
I prefer OMXPlayer. IMO plays better. Not for technical reasons just for what I experienced.

What happens when both are enabled? Which one is the preferred one?
