"Some paths dropped, only mono and stereo paths supported"

[LSNY]

"Some paths were dropped because only mono and stereo paths are supported".

Why do I see this when I open my sessions? A *very* small annoyance, but is there some way I can lose this? By setting the I/O to "default", etc? (I think I've done that), or some other way?

I dismiss it with one click, but I'm always interested in learning more about the I/O anyway.

Thanks to everyone in advance. This is the "note" I get...

Notes

Are you running HD software(required for surround)? Does your interface have at least 6 outputs that are mapped and available(also required for surround)?

The setup could not be more simple!
12.4
Not HD
It's a MacBook Pro, and my (USB) interface is an Apogee Mini Me (a good sounding relic). It has 2 inputs. All I ever need is Stereo Outs.

Can I change something somewhere so that PT knows that's all I've got / need?

Thanks...

Hmmm, did you open a session that was started on an HD rig? Trying to figure out why your sessions have surround IO when your rig doesn't). Any time you open a session from another system, you will need to spend a few minutes doing some IO "cleanup". As soon as I open any session from another rig, I open the IO setup and hit the OUTPUT tab and have a look(anything that has the incorrect name gets renamed). Then I hit the BUS tab, then click on the right column called "Mapped to Outputs'(or something like that) twice(not a double-click, just click once, then a second time). That will bring all output mapping to the top. Anything in italics is a non-working path which I delete. That usually takes care of things nicely(might need to change some IO back in the session)
