As much as I love using Apple Music and now Roon on various portable devices to browse and cue music for my DS DAC, I still rely heavily on infra-red remote controls to provide instantaneous control of play/pause, track skip and volume. There’s no bridge in my DS, so the Harmony remote is sending commands to either a SqueezeBox Touch (using as a Roon endpoint with USB connection to DAC) or Apple TV (Apple Music player, optical to DAC).
I’m interested in two other source options via USB:
PS Audio LANRover bringing audio from a computer in a different room
Directly attached iPhone or iPad using Lightning-to-USB adaptor
In both of those configurations my Harmony remote is unable to control play/pause and skip. So I’m wondering if it’s possible for the DS DAC to step in and help by declaring a USB multimedia keyboard device profile through its USB port and triggering the appropriate “keystrokes” when the IR receiver sees play/pause/forward/back commands from a remote. This would only happen when USB is the currently selected input on the DAC of course.
Hoping this is doable in a software update and of sufficient interest to people to make it worthwhile.
