I'm not getting any audio from the apps via the HDMI via ARC connection to my receiver. This occurred two weeks ago and was unable to resolve it, but ironically there was new firmware released that same day for my B6 (3/31/17) and this fixed the issue. However, now I again can't get it working after a TV reset and tinkering with the audio settings again. I tried to load the firmware again, but it appears this is not possible to forceable load the same firmware.
