Stream audio from PC to Android 7 over USB without creating a local network

Question

My work computer's DAC is awful, and I lost my USB DAC, so I'd like to use my phone as a DAC if possible, to enjoy average music quality while working.



However, my phone has a very poor internet connection at work, so I'd like to do it over USB (tried connecting over Bluetooth but it couldn't install the necessary drivers).



I looked at possible ways, and they all seem impossible to achieve. Soundwire requires admin rights and I unfortunately don't have them.



My phone is not rooted anymore for some reason but I could root it again if necessary. PC is running Windows 7.



Thanks for your help :)

Answer

If "specialized audio transmission channels" like Bluetooth don't work I would try the generic approach over TCP/IP:




  1. Connect your Android device to your Windows computer and enable ADB on the device (I assume adb is available on your Windows system).

  2. Install an streaming client on Android

  3. Install a matching streaming server on Windows

  4. Forward the streaming server's TCP port to the Android device via adb forward. This will allow to establish a TCP connection from Android to your computer tunneled through the ADB USB connection. For doing so no Wifi or cellular connection required or used.

  5. Connect the Android streaming client to the forwarded port on localhost and start audio playing
