[RPi2] No volume controls after installing on different TV

The volume controls on my RPi2 are ghosted, and the remote's Vol-up/down no longer works. The only difference is, I was using analog audio from the Pi before, now I am using HDMI audio only. In audio settings, I have tried both HDMI and HDMI+Analog. No difference. Why should that make any difference? CEC is disabled btw, as the TV doesn't support it.
