Hi Rob,

As stated in a previous mail the hdsp doesn't support interleaved mode, 
and this is the only mode available in pd when using alsa at the moment. 
There was a 0.35 version that had been patched to support 
non-interleaved mode IIRC. Maybe you can try to use the card through the 
plug layer, but performance will be suboptimal.
