Concerning your soundcard, you sould have HdspConf installed, no? There you
can simply choose the samplerate with buttons.
I don't have any experience with SPDIF, but I did recently started using an
ADAT (optical) device with the HDSP/Hammerfall, for inputs.
In my case, you have to set the ADAT device to 48 or 44.1 with a physical
switch on the back, and have the soundcard sync to that. (also a setting in
However, it seems like at 44.1kHz it's a lot less stable, it keeps losing
sync and resyncing all the time, at least that's what the gui shows, but
afaict it has no effect on the sound...
Lastly: I wonder if there isn't a way to downsample some subpatches to
playback the 44.1kHz soundfiles in a 48kHz environment?
