Unable to get sound to IOS device using High Sierra. The Parallels Access Sound output does not show as an option in the system preferences. Tested capability on same system in bootcamp "Windows 10" and sound passes to IOS device. I have uninstalled and reinstalled Access on both the IOS device and iMac. I have also verified the same behavior on "Test" account of a fresh install of High Sierra. This issues seems to be a High Sierra problem.
