Hi,
In my simple host program I've started to query the Name properties for
my output devices. I have 2 Firewire devices, Digidesign MBox 2 Pro and
M-Audio FireWire Audiophile. On both of these devices, the ChannelName,
ChannelNumberName and ChannelCategoryName properties are available in
the Output section. However, ChannelNumberName and ChannelCategoryName
seem to be always returning identical strings (to each other), for every
channel. The properties are not available on the Built-in audio.
I was expecting a string such as "1" or "One" for the ChannelNumberName
on Channel 1. What is the expected behavior? HALLab does not seem to
display these properties.
- Rick
