As reported at https://github.com/tigase/siskin-im/issues/56 there is no way to change the audio output device from the speaker. It would be good to be able to use different devices, ie. phone receiver (for voice only talks), headphones/headset, Bluetooth devices, or car audio.

The button to select audio output and logic to handle automatic output switching if previously selected output was removed was implemented.
