Hi. I'm sorry to ask a relatively basic question on what seems like a pretty high-powered dev list, but I'm having trouble finding the answer elsewhere. I'm using PulseAudio on Debian under Xfce. I want to bind keys to commands that raise and lower the volume (typically multimedia keys, though my current keyboard doesn't actually have these). That's it. There are a few discussions about how to do this online, including https://bbs.archlinux.org/viewtopic.php?id=46608&p=2 and http://crunchbanglinux.org/forums/topic/11392/pulseaudio-volume-control-with-media-keys/ The problem is, these commands only control one sink. I have two USB audio controllers and the internal sound card (and a virtual device to play everything together), and would like to be able to control whatever happens to be playing at any time. (Typically I have a music player going through a USB controller, and the rest of my system going through the internal card; I'm not usually listening to both simultaneously, but this is possible.) So maybe this is more of a question about shell coding, but either way, I'd think that it's something that would be of interest to many Pulse users. I had previously used Ubuntu, where the keyboard volume keys just worked, but it appears that the Ubuntu install uses amixer as a front end to everything, and that seems not to apply here. Thanks, and sorry if I'm missing something obvious.
