VAVA HDMI ARC to Denon Receiver

hi - I just got my VAVA 4K UST projector and have connected the HDMI3 ARC port to my Denon Receiver ARC input port. When I run any movie or video, the sound plays for 3-5 seconds and then it goes completely silent. Have tried both ARC settings in VAVA - PCM and RAW; same issue with both settings. No other devices connected on Denon. VAVA projector is connected to Roku on HDMI1.

Any help or guidance for troubleshooting would be much appreciated!

Thanks in advance,
Debbrata

Hi @debbrata Were sorry for the trouble this has caused. Kindly try to apply a factory reset to the device, and check the firmware version. Enable HDMI 2.0 on HDMI channel 3. Let us know how it goes.
