Until recently, I have been happily using the software provided by
Trevor Agus to control sound card volumes through Matlab in Windows
We now are using an RME Babyface, which has a similar mixer control to the other Fireface boxes (RME TotalMix FX). We have been able to control one of the volume settings (the local one) using the previous means in Matlab, but we cannot seem to get access to the main volume control (which overrides all the others).
I'd be grateful to know if anyone has faced this problem and come up with a solution.
Yours - Stuart
