Mac OS X Open Mash Issues
I've been corresponding with Claudio Allocchio, an Open Mash on Mac OS X user, for the past couple of weeks. He's run into a few problems with vic and vat.
When transmitting audio using vat from his iBook the loopback is delayed 0.5 to 0.75 seconds, and a receiving vat running under Linux is delayed up to 3 seconds. That's much larger than the 16 * 20ms ring buffer used, so I'm not sure where that's coming from. I've asked him to print out some ring buffer indices while testing to see if that shows anything.
He's also had a problem with vic crashing with the following error messages when he tries to use the "Mac OS X" source option. I'm guessing this occurs when he doesn't actually have a device attached; I need to add the appropriate checks to the code to ensure choosing "Mac OS X" does not do anything when there is no capture device.
