Soundtrack doesn’t integrate directly with the Denon HEOS app, but HEOS speakers support AirPlay, Bluetooth and line-in. To play music, you can:
- Connect a supported device to the line-in (AUX) port on your HEOS speaker. See the Denon HEOS manual for where to find it.
- Connect a supported device via Bluetooth.
- Connect an iOS device via AirPlay. Read more in How to connect to speakers.
