[BUG] Some WinMM tools (PocketMIDI specifically) showing bad port names due to port numbering

[Psychlist1972]

Describe the bug
Some tools are showing bad endpoint names. Possibly these are empty slots in the numbering, and whatever code they use to detect if it's a valid port is not getting the result they expect from WinMM

Note that this is with the more recent DP8 code including wdmaud2.drv. In the version that shipped with 27766 Canary, the names were not correct, but they also did not have bogus entries. These do not appear to correspond to any actual enumerated ports.

Pocket MIDI (input ports) (shows 35 bogus names at the top)

Surge XT shows correct input ports.

MIDI Tools will not open.

REAPER

mididiag.exe shows 70 total input ports, starting with #35, which corresponds to the bogus number of entries. It is followed by 35 actual ports. There are 35 devcaps errors, corresponding to the bogus count.
