Souncraft SI Expression USB-MADI issue (Resolved)

CAMBON CEDRIC's icon

Hi every one.
I'm running MAX 8.0.5 on mac osX 10.14.2 with USB-MADI combo card.
Sampling rate is 48000, Vector size is 512 and signal vector size is 64
With sf play help file, core audio driver selected and Souncraft MADI-USB as output device, output and audio processing doesn't operate...
On Max 7 that work but reading is accelerated...
Max console: no messages....

With Other softwares like garageband or quicktime, no problem so it's not a driver issue...(edit: Yes it is)

Any ideas?

Using ad_portaudio Core Audio driver solved my problem.
I don't know why but someone had the same problem on an Allen & Heath Device (https://community.allen-heath.com/forums/topic/sq7-usb-crashing-maxmsp)
