I have purchased Remote Access License recently.
Target systems activated with that license could not play any sounds.
As soon as I deactivate the license from that target systems and reconnect to them, I can hear all sounds from that target systems immediately.
After I activate License on that target systems and reconnect them, all sound gone again.
TeamViewer version : 14.1.3399
Seems some errors on sound processing logic when Remote Access License activated systems.
