Hope I'm not repeating something here, but this seems strange and new:

In pd37.1-test3, .pdrc audiodev numbers now have to be 2 greater than the /dev/dsp device I want, eg. to open /dev/dsp0 I have to use -audiodev 2,
while from the command line it still only has to be 1 greater than the device number

Slightly confusing, that's all
