I love little applications that just work™. Back in my Windows days, I remember coming across an application for network throughput monitoring at analogx.com (NetStat Live) and thought, "how awesome! I don't need anything complicated, just a small app that shows network throughput on my system... and here it is!" The same thing occurred today. Now that OS X 10.5 (aka Leopard) supports bluetooth stereo audio via the A2DP BT profile, I purchased a BT dongle that I can hook my headphones up to so that I'm not tethered to my office desk. (See the IOGear Audio Transport.) Once I got the dongle paired up with my workstation, I couldn't seem to connect to the stereo side of the headset. I was getting monaural sound, but not stereo. (Which, by the way, worked previously in 10.4. You could connect to a bluetooth stereo headset, but it would only pass audio in mono to the headset, not stereo.) I'm very familiar with how OS X handles audio input and output vis a vis System Preferences, but for some reason, I couldn't get stereo output.
I did a quick search via Google of the A2DP profile in 10.5 and found mention of Rogue Amoeba's SoundSource in a forum (I can't find the forum right now). I downloaded the app and had my problem solved in 30 seconds - literally. SoundSource is very good at showing sources and outputs for audio (the headset I'm using doesn't show up as well on their menu as in the Sound menu in System Preferences, but it is more intuitive). Just select and change source or output on the fly. It is that simple. To top it off, since it is free, there isn't a reason not to try it.
