Headphone emulation when streaming audio

[bropines]

• [x] I have checked that a similar feature request does not already exist.

Is it possible to emulate wired/bluetooth headphones when streaming audio? This would be very helpful when using audio modifications on your phone such as Viper/Dolby/MiSound. It's absolutely useless, but as an experiment.

I have attached a video of how the Viper behaves when plugging/unplugging the headphones.

It will also help people who sit on the PC with headphones. When playing from the speaker, the audio is in a mono channel. That is, streaming also in theory goes in a monochannel.

need this, when using messenger/discord it turns its audio into call mode, so it would be better to have it as headphone emulation instead.
