I can confirm that this issue still exists and the same workaround still works.
I am running Ubuntu 10.10 on an Asus eee 1005pe-pu17 netbook and connecting to Windows Server 2008 R2 (64-bit).
Desktop interaction worked fine, but no sound was being forwarded.
Taking the advice of the above post, I selected the option to redirect my local disk and sound is now forwarding from the remote system just fine.
