Hi,
I use an iMac as a monitor which is connected via mini displayport using a thunderbolt to thunderbolt cable. Since upgrading to Mojave I can no longer listen to the audio playing from my Macbook through the iMac's speakers; this worked fine before the upgrade. The iMac shows up as an output device, but switching to it results in silence. Does anyone have a solution to this issue please?

Try doing a PRAM reset on the MacBook with the iMac
in Target Display mode and connected.
PRAM reset:
Reset NVRAM or PRAM on your Mac - Apple Support
this can sometimes correct hardware interface issues.
