My TCL 55C715 received just received an OTA update just yesterday. After reboot, I have an issue with audio output through HDMI ARC. If I select PCM or Passthrough in the audio menu the volume output is too low even if the soundbar (Sony HT-RT3) is at max volume., only, if I select Auto in TV audio menu has a normal volume but just stereo. If I use Netflix in Auto the sound is 5.1 but in YouTube, the 5.1 test in Auto the rear speakers don't work
