Panasonic ST60 Series TV
MP2000 and MP2150 Portal
Sony HT-CT260H Soundbar
Portal --> HDMI --> Soundbar --> HDMI --> TV (HDMI Source marked as 'HDMI ARC')
I want to use the HDMI ARC (Audio Return Channel) option because it requires no additional remotes or setup. The same remote sends the volume up/down signal to the soundbar and it works great. After setting it up, the sound plays, volume control works fine. After I'm done watching, I turn the TV off, which also turns off the soundbar. I come back, turn the TV on, which turns on the soundbar, I have picture but no sound. I disconnect the HDMI cable from the portal for a second, reconnect and the sound starts working. If I disconnect the HDMI cable between soundbar and TV, still doesn't work.
Has anyone out there using a soundbar encountered this problem? Any tips on what else I could try?
