Since the July 11 firmware update on my Insignia smart TV (version 8.1.0), ARC audio has been having issues. When I turn the TV on, my Yamaha reciever does not register an ARC audio signal from the TV. Power cycling the TV does not fix the issue, but if I do a system restart from the menu the reciever will then pick up the audio signal from the TV and work correctly. This problem did not occur for the first two years that I owned the TV. CEC still works properly, but it seems as though whatever synchronization signal the TV sends to initiate audio transport is either not being sent, or being sent before the reciever is fully powered up.
