Android's Bluetooth stack supports various high-quality codecs like AAC, aptX, and LDAC. However, Bluetooth is designed for streaming audio from one source to one sink. While the "combined audio device routing" feature allows for streaming to multiple devices simultaneously under specific conditions, it does not provide the flexibility of a software patch cable for arbitrary app-to-app routing.
You can route your Android game audio directly into your PC, allowing you to capture it inside OBS Studio or stream it to Twitch.
Sending audio from your PC to your phone (or vice-versa) without quality loss.
Modern Android versions (Android 10 and above) allow apps to capture system audio internally.
If your Android device is rooted, you can bypass the sandbox entirely. This method delivers a true software-based virtual audio cable. Audio Modification Library (AML) virtual audio cable for android

Let us match real‑world scenarios to the most suitable solutions.
If you have ever wanted to play a YouTube video as your microphone input during a Discord call, or record internal system audio directly into a music production app, you are looking for a "Virtual Audio Cable." You can route your Android game audio directly
Connect the two: on the PC side, route the desired audio (for example, a game’s output or a microphone feed) through a virtual cable to the streaming app’s input. The streaming app then transmits that audio to your Android device in real time.
: Professionals use virtual cables to feed audio into Automatic Speech Recognition (ASR) software during remote simultaneous interpreting .
Sending Android audio to a PC or another Android device.
On iOS, is a well‑known inter‑app audio routing system. A similar concept exists on Android, though the ecosystem is less mature. Apps that support Android’s native audio routing APIs—such as those using the MediaRouter framework—can discover and connect to each other for audio playback. In practice, this works best within professional audio or music creation apps rather than general‑purpose system‑wide routing. If your Android device is rooted, you can

Desktop operating systems like Windows and macOS use global audio drivers. Software like VB-Cable or Loopback creates virtual input and output devices that any app can see. Android operates on a different architecture:
For those in music production, Audioroute is an open-source library that allows different Android music apps to exchange audio and MIDI data.
: That's it! Open any app that uses a microphone—Zoom, Google Meet, Discord, OBS, etc.—and it will now use your Android phone's microphone as the audio source.
