I'm replacing my soundbar with an AV receiver - the Sony STR-DH790 - but I cannot get ARC to work and produce sound. How do I get ARC to actually work for sound?
My soundbar was previously connected by ARC to the TV and worked perfectly - both the TV's control of the soundbar (power on/off and volume) and the audio channel worked.
With this AVR, the TV correctly turns the AVR on/off, controls volume, and controls muting. It even sends other commands (like arrow buttons). But no audio plays.
Right now, the setup is this:
Apple TV (4K) <---> TV <--(arc)--> AVR
In this setup
- The AppleTV can turn on/off the whole system
- The AppleTV remote successfully controls the AVR volume (so the whole chain of control is working)
- When the TV is set to use its speakers, sound comes out of its speakers
- When the TV is set to use the AVR for audio (via ARC), all three controls can control the volume of the AVR (the AVR's control, the AppleTV's control, and the TV's control), but no audio comes out. The volume indicator on the AVR itself does go up and down when the other controls' volumes are used, but still no sound.
- HDMI control AND EARC are enabled on the AVR and on the TV (and, again, I used to use ARC for audio on the TV). I've also tried other combinations and cycling things on/off.
- The speakers do work (tested using FM radio, and also the next section)
I also tested this configuration:
TV <---> AVR <---> AppleTV
In this setup, I got audio from the AppleTV though the AVR's speakers (though the 4K HDR signal was never successfully passed; for many reasons I have no intention of using this setup).
So how do I get it to actually listen to the audio over ARC?
Some notes:
- AVR firmware is current (1.171)
- HDMI 2.0 cable is connecting TV's ARC port to the AVR's ARC port
- TV model number: Samsung UN65MU800D
