[ardour-users] Spdiff stereo confusion

[Frank smith]

Hi Wolfgang

"Check the "Auto Input" Button in Ardour's editor"

Thats a new one I'll check that now.

As regards the 'hdspconf 'settings my card seems to be the Hammerfall light
and is not supported by any controller in Linux.

I still get the tracks I need though.

Thanks for your help.
