I think I tried all the usuals already, but I'm a recent purchaser of Acoustic Bridge. The trial seemed to work fine for a few hours.
But I have the issue that at random times the sound just 'stops'. This can be halfway through a Youtube video, or while listening to music. Just 'poof' silence. In the trayicon I can disable 'send audio when receiver is online' and directly my audio plays again through the _native_ (local) audio card (my laptop speakers in this case). When I enable 'send audio when receiver is online' again, the sound instantly comes from the remote receiver again.
It connects just fine and _starts_ playing audio without problems or hickups, so I'm guessing there isn't any firewall stuff. Otherwise why would it suddenly just stop midway through using it.
The connection is through ethernet, I entered the IP-address (which is static) instead of the computername in the Acoustic Bridge config, I already raised the buffers...
It seems there are more posts with this issue, from even years back. And the same guts seem to be used for the audio of Multiplicity where people also describe having 'dropout issues'. So surely there must be a solution by now?
