I've just installed 4.6.2 on my new Macbook and I'm getting an odd problem with MSP. Whenever I start a new patch (or open a saved one), it seems that noise (that sounds not unlike a crackly record) is being introduced into my signal chain. I've isolated the problem soley to Max (Garageband and Audacity are both fine) and it's not patch specific - simply connecting an adc~ to a dac~ reproduces it.
Now here's the funny part - it seems I only have to open DSP status and click on any option (not even change it) for it to go away. I have to go through this process every time I start Max else my audio input is noisy. Anyone else experienced this or something similar? I can post an example if necessary.
