Re: rdesktop with sound recording

Hi. It's difficult to say why this doesn't work. I assume that you have 
verified that this works with another client, so that you know that 
there's nothing wrong on the server side? If all else fails, you could 
consider using the rdpproxy to see what the MS client is doing. But I'm 
not sure how well rdpproxy works nowadays.

I can take a look later on, but I will travel the next few weeks.

Regards,
Peter
