Dear fellow A9G owners, I posted this back in February but don't believe anyone replied. Is anyone else having issues with soundbars (Sonos, Bose, etc.) and volume control?
My Experience with a Sony XBR-65A9G, Sonos/Bose Soundbars, and ANDROID PIE.
Around Christmas I upgraded to a 65" A9G. The TV itself is wonderful and I intend to find someone in the NYC area to calibrate it.
I paired the A9G with the Sonos Beam, subwoofer, and rear speakers. The Beam is connected via HDMI (ARC).
On the A9G, when the TV speakers are enabled, the volume control from any remote (Sony, Tivo, or Apple TV) is super fast and crisp.
When I try any of those remotes with audio switched to the Sonos Beam, the volume control has always been super slow. With the TV speakers, I can go from 0-40 in a 2-3 seconds, but with the Sonos it takes at closer to 10. Also, single-pressing "volume up" will go from 20 to 22 to 24 most of the time, but sometimes jumps by increments of 3 instead.
Holding down the volume up button is completely unpredictable - I see jumps from 20 to 28 to 40, etc. This all makes for a very displeasing experience with Sonos.
I tried upgrading to Android Pie on the Sony, and the issue got worse, not better. I upgraded the firmware on the Sonos, and no change. I tried a Bose Soundbar 700 and the issue was still there, pinpointing the Sony TV as the issue with HDMI/CEC. (I even tried turning on eARC on the TV since the Bose soundbar apparently has it enabled, but that did not help the issue).
Do others experience this issue as well? Why is it that in 2020 we still suffer with HDMI/CEC issues? Truly appreciate any feedback!
