Sound Card is Hercules RMX2

Debug [Main]: PlaylistTableModel(0x9083490) select() took 1 ms
Debug [Main]: guess the size of the window decoration
Debug [Main]: SoundManager::setupDevices()

[Daniel Schürmann (daschuer)]

The same happens if I set vinylcontrol to "None"

I do not face the crash if one vinylcontrol is not configured.
I face the crash only if BOTH vinylcontrols are configured.

[RJ Skerry-Ryan (rryan)]

Can you still reproduce? Could you post a backtrace for all threads?

[RJ Skerry-Ryan (rryan)]

Also, could you compile PortAudio from source so you have debugging symbols?

[Daniel Schürmann (daschuer)]

I have currently no access to the test system.
I will lower the priority since no one else has reported that and changing the sample rate is a setup only task.
