I started using Sonos Arc today with Sony Bravia XR X90J. I can see that there are mulitple layers of volume control.
- Volume level control in the App
- Volume level control that appears when phone’s volume buttons are pressed (appears as CAST volume control, I am using an android phone)
- Volume level control on TV which in turn controls the volume of Arc via HDMI eARC
- Master Volume limiter in the App advanced settings
What I have observed is that the volume level displayed on TV is not synronized with what it shows on the Sonos App. Also, Sonos App volume control overrides TV’s volume control - acts like a master volume knob! For example, I kept raising TV volume to 90% and yet, Arc was barely audible. I also checked the volume limiter in the App and it was at 100%. At first, I thought it’s an issue with the overall output of Arc, later I realized the regular volume control on the App was at 10%.
Shouldnt the App’s volume control increase when TV sends command to Arc to increase the volume via eARC port?
