Wondered if anyone has any suggestions about this?
Playing via Airplay to the SR7009 seems to limit the volume to 74% of the Marantz available total. I can manually raise the volume on the Marantz above that level but as soon as the volume is readjusted in Roon (either in Core or Android phone, even by just 1/100th of Roon Volume Slider) it immediately reduces the volume back to 74 max on the Marantz.
Settings in Roon for the SR7009 are
Volume Control: Device Volume
Volume Limits: 1 - 100 for Comfort & Max
Multichannel Mixing: Downmix as Needed, or Channel Mapping Only (either has same issue)
DSP: Enabled or Disabled (either has same issue)
Driving me batty. Any suggestions appreciated!
