[Jackaudio] Question about target drivers

Hi, I have a question about the difference between 1: Targeting a driver using Port Audio 2: Selecting an interface in Jack Control This is the situation. I have PortAudio setup to target ASIO4ALL: "C:\Program Files\Jack\jackd.exe" -R -S -d portaudio -d "ASIO::ASIO4ALL v2" -r48000 -p512" What I really want to do is target Dante: "C:\Program Files\Jack\jackd.exe" -R -S -d portaudio -d "ASIO::Dante Virtual Soundcard (x64)" r48000 -p512" When I try this, i get the following error: * Could not connect to ASIO::Dante Virtual Soundcard (x64) using default. So, I tried thhe following. I left my PortAudio to target ASIO4ALL And in Jack Control I selected Dante as an output under advanced settings. No errors this time. So what is the difference between "targeting a driver" and selecting a default IO? Thanks in advance. Marijn
