Hi List,
some of my students reported problems with pd using external firewire interfaces on MacBooks with OSX 2.6.8. A sine wave from the "test audio and midi" panel is very distorted.
We encountered this problem on a consumer ESI Interface and on the RME Fireface. We tried different pd versions (0.43 and 0.42 branches, vanilla and extended) using coreaudio and jack with the same result. The internal sound card and standard usb interfaces sound fine with pd.
The problem seems strange as the firewire interfaces work without any problems with other audio applications like logic or live.
I tried to google this problem but couldn't find anything. Is this a known issue and can someone comment on this or give any advice how to proceed?
Yours, Orm
