Hi,
I noticed a strange behaviour in Yosemite (haven’t tested prior versions yet)
related to hog mode not functioning when only 1 output device is present.
Using a Macbook Pro, with no Airplay or other potential output devices
connected, I get my application to hog the Built-In Output. My logging reports
this as having worked, and HALLab reports the oink event on the device. With my
application hogging the output, I’m still able to hear output from other
applications (Skype, etc…) If I add a second output device then hog mode works
properly with my application hogging one device and the system automatically
re-routing audio to the second device.
The interesting thing is, if instead of using my application to hog Built-In
Output, I use HALLab itself, then everything behaves as I would expect. In
other words, with just Built-In Output available to the system, no sound from
any other apps. The notifications in HALLab are the same as those from my
application.
Just in case, here’s the selector I’m using to set hog mode {
kAudioDevicePropertyHogMode, kAudioObjectPropertyScopeGlobal,
kAudioObjectPropertyElementMaster }.
Any ideas what might be causing this?
