I have an LG OLED C1 TV connected to a Bose Smart Soundbar 900 that loses audio after skipping 30 seconds on my TiVo DVR only when connected via eARC HDMI. If I switch to optical it doesn't happen. The only way to recover audio with HDMI is to reboot the Soundbar. Rebooting the TV has no effect. Sure seems like a bug. I tried doing a firmware update and it never completed. It kept showing the moving LED lights for over 12 hours. Yet another bug?
