Change samplerate to 44100 Khz?

[joreer]

Hi guys, first: love this solution! I have 2 Pi's and would like to use them for a local radiostation. 1 goes into the studio, the other is for reporting live from elsewhere. The "external" pi is connected to a Behringer USB mixer: works like a charm. But the "studio" pi is connected to our main mixer (DHD 5200).

There is sound coming IN from the pi into the mixer. But no sound coming OUT of my mixer into the pi. I think it has something to do with the sample rate in the Pi. Because my studio-mixer is providing everything in 44100 Khz. I cannot choose this option in Sonobus on the Pi.. And also in Audacity i've got no signal coming in.. Does anyone know how to fix this? Thanx a lot! :)
