This has been discussed many times.

Currently the only ways to get pcm device sharing, I assume you mean 
using multiple devices as one virtual device are to write it up in your 
.asoundrc or use the patch which has been submitted but not applied to 
jack for this purpose.

The former is a little tricky to grok but it has been shown to work. The 
later requires a bit more of a deeper understanding of jack and coding.

There is info in the online docs. Just click on the link in the asoundrc 
  section for your device and the file is explained in depth.

If however you mean hardware mixing (multiple streams at the same time) 
then it is dependant on the device and the manufacturers supplied tech 
details.
