Hi,

Chrome users are occasionally hitting a problem where AURenderCallbacks stop after a system resumes from sleep. We've seen this with both default and AUHAL subtype output units over a variety of OSX versions and hardware types -- even plain up-to-date retina MBPs using nothing but the built-in speakers.

We're trying to figure out if we're doing something wrong or if this is a bug. Has anyone else encountered this issue before?

We're only monitoring kAudioHardwarePropertyDefaultOutputDevice for changes, are there other properties we should be listening to which might indicate when a stream restart is necessary?

Perhaps we should be listening for some device level properties like kAudioDevicePropertyDeviceIsAlive or kAudioDevicePropertyDeviceHasChanged?

The code is here if anyone would like to take a look:

https://code.google.com/p/chromium/codesearch#chromium/src/media/audio/mac/audio_device_listener_mac.h

Thanks in advance for any assistance.
