I'm running OSX Panther 10.3.9 with an M-Audio Firewire 410 interface.
I can record anything and everything into Audacity in 2-channel,
32-bit float. However, when I try to playback my recordings, or indeed
play anything in Audacity through the 410, I get the message "Error
while opening sound device. Please check the output device settings
and the project sample rate." I've adjusted the project sample rate,
cracked open the Audio/MIDI Setup utility (I can't change the
channels/bits). I'm at a loss. Help!
