I do not know what wmidids exactly is but it is definitely not needed in order to use MIDI with Wingroove together with the HD Audio driver.
In order other Midi software to use Wingroove you have to set a new preset in Win 3.1 Midi mapper for Wingroove and set it as default.
As you can see in my test video Midisoft Recording Session can use Wingroove without problems. Default Win 3.1 media player also uses Wingroove as default Midi out this way.

Thank you very much. I reinstalled WinGroove, and it automatically creates a preset in which all midi channels are mapped to "WinGroove". Now the MIDI files play properly via windows media player, but on starting Chip's Challenge and enabling music, it shows this error:

"MIDI Error on file chip02.mid: The specified MIDI device is already in use. Wait until it is free, and then try again."

And once I close the game and double-click chip02.mid, it plays normally via windows media player. It's a bit confusing - do you have an idea what's going on? Do you get the same error (in case you get the chance to test Chip's Challenge on your end)?

Hi,
Check system.ini in your Win31 folder. In the 'driver' section you should have something like this:

1[drivers]
2...
3wave=hda2.dll
4...
5Midi1=C:\WINGROOV\WGMMDRVR.DRV
6Wave1=C:\WINGROOV\WGMMDRVR.DRV

That is you have to have 2 Wave devices referenced. Then in your Control panel -> Sound Mapper section you should check that you have both 'WinGroove WaveOut' and 'HDA Sound'.
Also check the Wingroove help file and make sure that you read carefully the Always able to play/Always active section:

Hi,

Thank you very much! I subbed to your channel (also good song for WinPlay3 test). So now I can play Chip's Challenge with both midi and sound effects. In your video I can see you have extremely low latency in that "Slam!" game. But when I set a low latency in WinGroove setup, the sound starts breaking and popping. The minimum non-problematic latency I could see was 250 ms. Did you follow any specific procedure to get an even lower latency?

You're welcome!
Latency setting in Wingroove only affects Midi playback. It has nothing to do with wave playback ( and thus the Slam game).
The only specific setting I use is related to startup wait times. You can read about it in this thread:
