Bounce to Clip Error

Has anyone seen this?

DirectShow Error [0x8004022A]
This filter does not support the current audio format. It may require a different number of channels (e.g., stereo instead of mono) or a different sample rate.


I recorded a simple guitar track at 48 KHz like I always do. I selected the best clips from a few takes and deleted the clips of takes that I didn't like. I wanted to bounce it to one clip by selecting all of the clips, right-clicking and choosing, "Bounce to Clip(s)." I do this all of the time, and I don't remember getting this error.

More information:
It is one track with multiple clips recorded at 48KHz. I checked my external clock and the Audio settings in Sonar. 
I am using Sonar X1c. 
I use this technique pretty frequently, and I have yet to have the problem (so far as I remember).
The takes I referred to were recorded into one track while looping. I expose them by displaying all layers. I split and delete parts from takes that I don't like to get one good overall clip.

I worked around by bouncing to a different track, but if someone can figure this out, I'd like to keep the old method.


Thanks in advance for any suggestions, ideas, etc.

Sorry, It is X1d.
