Audio out-of-sync when using passthrough on google TV chromecast 4k



Google TV Chromecast 4k HDMI output goes into my AV receiver (supports 5.1/7.1 DD/DTS and worked fine in passthrough on Kodi running on PC)

On the Google TV chromecast, if Kodi is configured for passthrough, the video always lags the audio by about 1 second (varies).

Is this a known issue ? Any known fixes/solutions?

I tried turning off passthrough but I get other audio issues (audio stutter or loss). Running Kodi v21 (had the same issue with v20)

Thanks
