I ask the above, as my LG 49SM8500PLA TV, which I've had for about a year or so, routinely throws two hissy fits (not at the same time, from what I've noticed):
1) It flags Freeview channels as having 5.1 audio, which is wrong (ITV HD, C5HD, Talking Pictures, etc.)
2) Stuff flagged as having 5.1 audio on Amazon Video and NowTV only plays back in stereo
My TV is connected to a Yamaha YSP4100 sound bar. My first thought, given that the bar is perhaps 10 years old, was that it was starting to fail. However, all other sources connected to it work fine, and a power cycle, when the LG was mis-flagging audio, made no difference to the problem.
I can clear both (1) & (2) by removing mains power to the TV, but it's a hassle trying to unplug and plug-in cables (the proverbial rats' nest, that we all know and love).
The last time that problem (1) happened, which was earlier this week, rather than bouncing the TV's power, I toggled the HDMI ARC setting from Auto to PCM and back again, which seemed to fix the issue. At that point, I did wonder if I should be using the PassThru setting rather than Auto. The only other bit of kit connected to the TV that supplies 5.1 audio is a NowTV box. The TV seems to have no problem routing audio from the box into my soundbar.
For problem (2), the next time that this happens, I'll also try toggling the HDMI option, and I'll also force quit the offending app. to see if I can avoid pulling power.
I suspect that a previous firmware update might have introduced the above issues, as for the first 6 months or so the TV and bar combination was fine. That, or I have marginal hardware or a weird fault somewhere. I further suspect that the two problems are somehow linked, given the audio switch around, but I've never investigated the two issues at the same time, having always pulled the TV's power when one or other surfaces. Anyway, I'd appreciate any LG TV owners thoughts on the above problems. Is PassThru a better bet? Has anyone experienced the same or similar issues? Any insights would be greatly appreciated.
Cheers.
