Mostly towards John Clements: I thought I'd take a look at RSound to make a little "do X for 30 seconds *beep* wait 10 seconds *beep* [repeat]" program. Trying (play ding) gets me the stuff before the "found 2 host APIs" with no sound. Running diagnose-sound-playing gets me a beep after the "trying api paALSA" but nothing afterwards. There isn't any documentation for setting the API to just use paALSA, so... what might be going on here? I'm running xfce 4.10 - xubuntu 12.10 64 bit.
I have all the pulseaudio modules that aptitude listed.

If playback at 44100.0 failed and playback at another sample rate succeeded using Windows 7, you probably need to manually set the sample rate of that playback device to 44100 Hz, by right-clicking on the volume icon and then digging through menus (properties, advanced). -Ian ____________________ Racket Users list: http://lists.racket-lang.org/users
