- Thread-topic: Choppy Audio Through Core Audio
We’re having an issue that we cannot reproduce in house, so I wanted to bounce it off everyone here to see if I can get any feedback that may help.
After several hours of leaving the computer running, possibly sleeping the computer, etc, users report that audio through core Audio begins to degrade when using our USB Audio device. It becomes glitchy. The interesting thing to me is that re-plugging
the device does not fix the issue. Only restarting the machine fixes the issue once it gets into this state.
What, if any information would be stored in Core Audio that could affect the next replug of our device? Does Core Audio store clock timing information? Is there any other known reason that Core Audio behavior would change over time? Our sampleoffsets are
fairly aggressive so I’m wondering if maybe it could have something to do with that.
Also of interest is that almost every user reporting this is running an 8-core MacPro. Has anyone seen anything like this?
Thanks in advance for the help.
