Yesterday it worked - could read and play MIDI through

Today, when I started up the system, KDE tells me:
Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such file or directory)
The sound server will continue, using the null output device.
I use ALSA and the system is usually set for Autodetect, but get the

I fix it?
Running Debian testing. Did not update anything between the time it
worked and now.
