Audio stream switch on gesture? or button?

[yoko1998]

Hi, it is very unnoing when BSPlayer misdetect which audio stream should be used by default. After that you have to select audio stream manually, and re-select again each time BSPlayer resets playing - on switching apps, on restoring after lost focus etc.
And this requires several precise touches.

Could it be possible to set audio stream switch onto some gesture or quick interface button?
Thank you in advance.
