I have a device driver that offers 3 channel count settings (say 4, 8, 16).
Under 10.6.8:
Set channel count in Audio Midi Setup. Reboot. New setting is preserved.
Under 10.7.4:
Set channel count in Audio Midi Setup. Reboot. Returns to some default
setting.
The default setting returned to seems to be in
/Library/Preferences/Audio/com.apple.DeviceSettings.plist ("channels per
frame" field). Based on the timestamp, this seems to be updated (only)
during the reboot cycle, either on the way down or up.
I tried manually editing the values, and they were overwritten by the next
boot cycle.
Any thoughts? I'd really prefer the 10.6.8 behaviour.
