I can't adjust the volume in Roon arc today. I've got a Sony Xperia 1 vi, Grado SR80s and iFi Go link Max. To get it to play lossless I have to unplug and plug in again, then toggle the usb driver off and on. After that it works but no volume control on the phone (slider moves but no effect)
Is volume control still working properly through other apps (youtube, etc.)? Is the issue the same if you try to reboot the Xperia device (power off, wait 30s, power back on)?
