According to others I've talked to here involved in the Terminal Services
features of Windows Server 2003, this is by design. I agree that some of the
API behavior here is less than perfect (e.g. the RDP audio device and other
devices ideally should not be represented in the waveOutGetNumDevs and
waveOutGetDevCaps functions) but, in any case, this is how it is.

Yes, I can connect to the console session using "mstsc /console". But
I cannot understand why I cannot use a general Remote Desktop
connection specifying "Leave at remote computer" option when connect
to Windows 2003 server. Microsoft documentation said nothing about
this issue.
And I see the same Windows 2003 Server behavior: regardless of "Remote
Computer Sound" selection ("Leave at remote computer" or "Bring to
this computer"), Windows 2003 Server ALWAYS presents only RDP Audio
Driver as a valid device. Other devices are counted (waveOutGetNumDevs
returns 4) but only "RDP Audio Driver" name is returned by
waveOutGetDevCaps. For other three devices waveOutGetDevCaps
returns MMSYSERR_BADDEVICEID.
BTW, RDP Audio Driver does not work too. waveOutOpen always returns
MMSYSERR_NODRIVER, regardless of an audio format.
Regards,
Eugene
