On the TV, what is Digital Sound Out currently set to? What about DTV Audio Settings? What other options do you have under each of these settings?
Is there a HDMI Input Audio Format setting available on the TV?
Have you set the TV Sound setting on the Switch to Surround?
FYI… I’m pretty sure the B7 only has HDMI ARC not eARC.
My Sound out is set to: Audio out (optical/HDMI Arc) under digital sound it’s on auto instead of PCM. Simplink is on.
other options:
LG sound sync (optical)
LG sound sync bluetooth
Audio out (line out)
Wired headphones
DTV Audio settings further down is set to Auto, with a grey check mark on MPEG
Other options:
Dolby Digital
Dolby Digital Plus
HE-AAC
I can’t find an HDMI IAF anywhere.
When I tried it out, I set the switch to surround. I got the sound test with sound from left and right, but silence for the rest.
You are right about eArc and Arc..
Thank you!
Try setting DTV Audio Settings to Dolby Digital or Dolby Digital Plus.
I think what is happening is the Nintendo Switch uses LPCM audio. Only a TV equipped with eARC can pass through LPCM audio. This is why you are limited to Stereo PCM.
Unfortunately, neither of those Dolbys worked..
I’m trying to find out why Sound mode settings, which is set to Standard (user), is greyed out.
