I am testing patches with a Logitech AK5370 usb microphone. After about one minute the sound becomes dirty and full of clicks until sound is restarted. Then I get just another minute of pure sound.
This happens for any patch with microphone input, like a simple patch with 8 different delays. There are no other choices than 44100 for sample rate, both in DSP status and Audio driver setup, so I can’t know if the microphone is using a different sample rate.
The microphone is new and doesn’t seem to make any noise in skype. It didn’t work at all in MaxMsp 4.5, and the upgrade to MaxMsp 5 didn’t solve the problem. I have the same problem also with no extra externals installed.
I have tried this both on an ibook G4 1.33 Ghz 768 Mb ram, and a macbook 2.16 ghz intel 1 GB ram. It made no difference, but both were running Osx 10.4.11.
