Hi Lee, > You just need to patch STK to allow plughw devices to be used, or give > up and run at 48Khz. There's no other solution. Thanks for the concise and clear answer. I decided to change my code and run at 48kHz. I am now facing a new problem. If I run at 48kHz with the old soundcard everything works fine. If I switch to the Terratec I get quite some problems. The system slows down a lot, things got better switching the module param nrpacks=1 and making the buffer larger, but it still clicks and the system is still very slow. I am currently using the blocking version of the STK real-time audio classes. Despite the fact that I have them in a separate threads, the new card is slowing also the other threads. Shall I consider switching to the non-blocking callback methods? If so, why? What else shall I look at to make my system perform normally? I'll be happy to provide more info if that helps.
