In the patch below, if I first load a stereo file, and then examine 

the buffer (double click), I _see a stereo file.

If I then load a mono file, I see a mono file.

But if I then load a stereo file again, it's only loading one channel.

Same thing if I use the read message to open a stereo file - only one 

Is there a way to force the buffer to load the right number of channels?

That's what I started with. I changed to [read] with the thought that 

it would behave better. Anyway, I just tried again with replace, and 

buffer is still remaining as one channel after loading in a mono file 

start with 2 channel buffer - load in mono file - buffer becomes 

load in stereo file - buffer remains single channel (at least as 

tested by double clicking on the buffer~ object to open the viewing

Let me be clear -
start with 2 channel buffer - load in mono file - buffer becomes  
single channel
load in stereo file - buffer remains single channel (at least as  
tested by double clicking on the buffer~ object to open the viewing  
window.
Here's the patch I'm testing with...

When using read messages giving size & number of channels to read (as documented in buffer~.help), buffer seems to have a bug indeed (Max 4.6.3 or Max 5, OSX.5.3 Intel).

Solution is to use a replace message with no argument.

But you can only open all channels...

Here is a proper way to force buffer~ to mono from a stereo soundfile, preserving the file path, but using 3 buffers instead of one and mxj buf.Op

buffer ignores number of channels?
