audi a5 2016 intermittent sound issues

ZTAudi  audi a5 2016 intermittent sound issues
hi all,

i have a 2016 audi a5 here with a b & o sound system and a strange intermittent fault.  that fault being the sound not working all the time.  all the mmi system works but just no sound.

the fault does have a pattern, if we start the car and the sound is working it will continue to work until the car goes to sleep.  once the car is woken back up we will have no sound until the car goes to sleep again.   and the the cycle continues.

sound - let the car go to sleep - wake the car - no sound - let the car go to sleep - wake the car - sound

i have used odis online to check all coding etc but it is still the same

has anyone come across this issue before and found a fix.

thanks in advance

If i've helped don't forget the magic buttons, thanks + rep  yes yes

I had very similar problem in one car and the problem was in radio unit ,adress 56.
We replaced the radio and problem was gone.

originally there was no sound at all, we replaced the radio with a used one and now this issue.

everything is coded correctly as we did it with genuine odis online
