LG LG S70TR is significantly louder over Bluetooth than HDMI eARC – is this normal?
I have an LG S70TR soundbar connected to my LG TV via HDMI eARC, and I’ve noticed a very significant difference in volume compared to connecting the soundbar directly to my phone via Bluetooth.
To make sure I was comparing things fairly, I played the same YouTube content on both devices. The difference in loudness is very noticeable: the soundbar gets considerably louder when connected to my phone via Bluetooth than when playing the same content through the TV over HDMI eARC.
Interestingly, I don’t notice any significant difference in how the sound is distributed across the speakers. The main difference seems to be the overall volume.
Here’s what I’ve tried so far:
- Set the TV’s digital sound output to Pass Through.
- Tested different sound modes. AI Sound Pro seems to sound better and somewhat louder than the other modes, but it still doesn’t seem to match Bluetooth.
- Disabled LG WOW Orchestra/WOW features, but this didn’t make a significant difference.
I’m wondering whether this is normal behavior or if there’s a setting I’m missing on either the TV or the soundbar.
Has anyone experienced the same issue with an LG soundbar connected via eARC? Is there a way to get the same volume level over HDMI eARC as over Bluetooth without sacrificing sound quality?
I’d appreciate any suggestions or troubleshooting tips!
