I have a small app which get all avaible audio devices and sources
and put it in menus. I used HALLab for example to write the code, but
in objective-c++ instead of cpp.
I use this app for 2 years now and all works well (on PowerPC).
I recently get a MacPro and I notice that I have trouble with getting
kAudioDevicePropertyDataSourceNameForIDCFString after changing a source.
I have listener in my app. When data source or device property
change, I update my menus (rebuilding them from scratch with a
complete discover of device and source).
The first load of app build a complete menu without error. But when I
change source, for example I put my headphone on front panel of
MacPro) the data source name given by
is nul !!
I got an OSStatus error : 1852797029 -> ('nope')
It's very strange because I use the same function at the start of the
app which return me a valid name. When the datasource change I
destroy and re-create a full new object handling the property of
device and attached datasources...
I don't have this problem on HALLab. I control the device ID, data
source ID, channel, sizeof AudioValueTranslation between the two app
and they are exactly the same when the problem occurs.
I don't know what to do now. Have someone an idea?
Thx
David
