I recently purchased a new Onkyo receiver, Sonos speakers and amp. The installation and configuration was fairly simple and straight forward. I am very happy with them and everything is working together, but I have not been able to able to overcome the volume limiting. I have Polk audio speakers and anyone that has had Polk audio speakers knows you need a good amp, they are very power hungry and will not even operate until you have raised the volume to a higher level.
I have volume limit on sonos turned off and I have set my Onkyo amp to start at the volume that will start to power the speakers. When I play music from the sonos app to my onkyo / polk audio the volume slide starts are near ½ to ¾ volume on the slide bar. Leaving only about ¼ of the bar remaining to raise the volume. When I move it to the max volume on the sonos app it is really only about ½ volume limit on the amp. I can still adjust with amp controls. In addition the sensitivity of the volume control with the sonos amp is too sensitive, a slight adjustment with the sonos slide bar will take you from not hearing anything to very loud with very little adjustment
How do I adjust the volume limiting so I can use the full functionality in my amp?
