Hi all,
We have been having some sound issues using rdesktop over our network (especially with lots of screen updates coming at the same time), and we thought we might have a try at using a sound format other than WAVE_FORMAT_PCM so that the sound takes up less bandwidth and see if that makes a difference.  For instance, our Windows terminal server advertises that it can do MS ADPCM, among others (Windows Server 2008 R2).  However, if I tell the server that the rdesktop client does only WAVE_FORMAT_ADPCM, I get the ping back from the server, but then nothing after that.  It doesn't seem like rdpsnd_process_packet() is called again.  So I haven't started doing anything to try to decode sound in a different format, because we're having trouble even receiving the packet.  I was wondering if anyone else has explored this kind of thing before?  No use barking up the wrong tree if it's already been done...
