| Dear All,
I've read many previous posts but am still having trouble getting my music device AU to show as a multi-channel output AU in Logic 8 (Logic 7 was fine).
Here's what I've done:
- subclass AUOutputElement to support GetChannelLayoutTags() and GetAudioChannelLayout() - overide CreateElement() in my AU to create my subclassed output
Here's part of the output of auval:
-------------------------------------------------- FORMAT TESTS:
Reported Channel Capabilities (explicit): [0, 2] [0, 8]
No Input, Output Chans: 0-2 X
# # AudioChannelLayouts (2), Output Scope: ChannelLayout is Writable: F The Unit publishes the following Channel Layouts: 0x650002, 0x6F0008,
Is Audio Channel Layout Available: Mono Stereo Binau. AU_4 Ambi. AU_5 AU_5_0 AU_6 AU_6_0 AU_7_0 AU_7_0F AU_8 AU_5_1 AU_6_1 AU_7_1 AU_7_1F X X
* * PASS --------------------------------------------------
It looks like the channel layouts are being correctly reported by my subclassed output element.
But despite SupportedNumChannels() correctly reporting 0-2 and 0-8 channels, auval is still only reporting 0-2 channels.
What am I missing?
Thanks, Malcolm Haylock
