Client sound (mic) input via ICA/PXES?

Our PXES Citrix solution is working nicely thanks to the help of everyone on
this forum.  
 
The next issue that has come up is - inputting sound via client microphone.
this would allow our French and German students to record their responses on
some educational packages.
 
I've searched around on Citrix forums and I'm unclear whether this is
supported yet.  I would have thought that it would be supported in this
world of telesales etc. 
 
Anyway, *if* the ICA client supports it, would PXES be able to handle it?
Or does RDP support it? If anyone has any experience of this issue, we'd
appreciate it!
 
Many thanks,
