Panic when getting outputstream from headphones when other audio is playing

[merelymyself]

Code: OutputStream::try_from_device(&vec_of_acc[0]).unwrap(), wherein &vec_of_acc[0] is of type Device.

It works when no other audio is playing, but when I have cmus or YouTube active, everytime I try to run it it throws the following error:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: DefaultStreamConfigError(DeviceNotAvailable)', src/music_backend/device_handling.rs:82:55
