Playing audio on different devices?

Question

I have a USB headphones connected to system. So now my system has two different audio output devices (one internal speakers and other is USB headphone). Though it is possible t choose the default the output device. What i am interested is play different audio on each of the device at the same time. In other words i am looking for a program solution which gives freedom to choose the device on which the audio should be played. By any means, using any library is this possible?

Answer 1

If you use sounddevice.play(), you can simply specify the desired device with each call.

You can either use the device ID (e.g. device=3) or a substring of the device name (e.g. device='headphone', if that's part of the device name).

You can get a list of devices with:

python3 -m sounddevice
