Unable to send multichannel PCM audio from PC to LG B6

Recommended Posts

I recently purchased a B6, and came to realize my good old AVR (a Denon 1612), featuring HDMI 1.4, won't do HDR pass-through, so intending to keep the Denon, I switched to having the TV in the middle, instead of the AVR as I did until today.  I have managed to get audio sent from the TV to the AVR via both ARC and optical, multichannel working fine, but the problem came when I tried to have multichannel audio from the PC to the TV.

The problem is, the PC (using a GeForce 1070) sees the TV as accepting only stereo PCM audio, and only allows to select stereo in the device's speaker setup. Needless to say, I need 5.1 PCM to get multichannel audio in PC games.

I even tried using an EDID override, copying the audio capabilities from the Denon to the TV, which allowed me to have Windows think it can send the TV any of the stuff the Denon takes, but even then any audio from channels other than left front and right front  is lost along the way to the AVR. My guess is that for whatever reason, the TV is decoding the stream and only letting L and R through.

On the bright side of things, multichannel pass-through does works fine for DD and DTS streams, allowing to watch a movie on the PC and have semi-decent multichannel on the AVR. Dolby TrueHD and DTS HD, though, are a no go, even using ARC (optical obviously doesn't support HD audio).

So yeah... Any ideas? Suggestions?

I'd like to think I won't be forced to buy a new AVR just to have it pass through HDR, so any help will be appreciated.

      Hi everyone,
      It seems that the Window command "Read on device" don't work properly with My LG UH661V.
      The problem:
      Once the video start, it will just stop and get back to main menu after a minute or so. If I try to change the video timeline, it stops immediately. But it seems to only happen if the file content isn't longer than ~30 minutes. Minor issues:
      With AVI files and MKV files, the timeline just don't work. Trying to change the time just result in an error message on the TV. Other points:
      The WebOS is up to date. Windows OS is Windows 10, up to date too. Tried to read on Xbox One and a Samsung TV, and it works just fine. Only happen with LG TV. Any thoughts on this?
      Thanks !

      Hi,
      i have a Pioneer 5.1 receiver connected via HDMI-ARC.  Sound by watching live-TV is ok, Dolby Digital output too.
      Watching Netflix or Amazon Dolby Digital output is not working and gets very heavy sound failures. Sound's working only in PCM! That's very poor.....
       
      My settings:
      Audio output via arc "automatic"
      DTV-audio settings "automatic"
      firmware 04.70.45
       
       
      Any solutions??

      Hello, I have been enjoying my OLED B6 WebOS 3.0 model for half year. Just out of the sudden my two Windows machines with LG SmartShare app cannot discover my TV anymore. So I can still stream movies if I go to my TV Photos and Videos app and it detects my computer media service(s), so I can select desired video and watch it. However I cannot start streaming from my two Windows 10 computers - each computer detects another one, however TV is not detected, I cannot right click on video file in SmartShare app and find TV set under "Play to" menu.
      My TV and main PC have wired connection with my router, another Windows machine is laptop with WIFI only. I have tried to disable/enable TV's wired and wifi internet settings... no luck ;-/

      Any hints?..

      Great picture but how to fix lip sync problem, only on ABC network channels, coming from Spectrum Hawaii?  Same cable box into my older Panasonic Plasma, using same HDMI cable: do NOT see lip sync problem.  What am I missing, or what is different coming in on the cable that bothers the LG set but does not   bother the Panasonic TV?
