Hello,
I'm upgrading some code I didn't touch for years to get rid of deprecation
warnings, and run into a regression.
After the upgrade the listener callback that's supposed to catch user-induced
changes to device sample rate settings is no longer being called (on 10.9.5
using the 10.10 SDK). As far as I can tell the AudioObjectAddPropertyListener
completes without error when called with
AudioObjectPropertyAddress prop = {
kAudioDevicePropertyActualSampleRate,
kAudioObjectPropertyScopeGlobal,
kAudioObjectPropertyElementMaster };
Googling the issue suggests that I'm not the only one who's observed this, but
doesn't provide any answers.
Is this a known issue, and is there a solution? I'd be OK with conditional code
if the feature works again from 10.11 or 10.12 (or 10.1x) onwards.
Thanks,
René
