iPad to control Mac Pro computer audio system

Technology

Mine

• MacPro macOS
• 11.0.1 Big Sur

My wife's

• iPad Pro
• iPadOS 14.2

Stereo system

MacPro has a hardwired digital connection to my stereo system's DAC. No other available inputs (wireless or bluetooth) into the stereo system.

So, I can not send music directly from any other device to the stereo system. The stereo has no other inputs remote or otherwise.

I use Apple's Music app. Works perfectly.

Goal

Enable my wife's iPadPro to remotely access my Mac Pro's Music app. So she can play music on the attached stereo system.

Note: She has a different AppleID than I do, but I could let her use mine if it would help.

Thoughts appreciated.

Solution 1:

This is kind of half an answer as it's been so long since I actually did this that the method is a bit hazy… Apple's iTunes Remote - https://apps.apple.com/gb/app/itunes-remote/id284417350 There's a one-off sign in procedure to authorise 'foreign' remotes.
