Hi, I'm wondering if there is any way to permanently bind an application to a specified sink. I have 2 audio output devices; a built-in soundcard which is connected to my desk speakers, and a high-end external USB-audio device that is connected to my main amp and living room speakers. What i'm looking for is way to always route my mp3/flac player applications (rhythmbox, audacious, etc) to the external audio device, while all other applications use the default sink, which would in this case be the internal sound card. At the moment i'm pointing the streams to the appropriate sink using pavucontrol, but i have to do that every time the stream starts, otherwise it will revert back to the default sink. So i'm basically looking for a way to make these choices permanent, any ideas?
