ARDOP cannot find soundcards with winemono

[WheezyE]

ARDOP is a small open-source sound modem program that and comes pre-packaged with Winlink Express.

When winemono is installed, Winlink constantly auto-restarts ARDOP because no sound is detected after >10 seconds. dotnet46 works.

ARDOP/WinlinkExpress+winemono reports "*** FAULT PLAYBACK DEVICE SETUP, DEVICE NOT FOUND IN WINDOWS ENUMERATED PLAYBACK DEVICES".

This issue is present in old versions of ARDOP too when run with modern wine-mono.

• Winlink 1.5.13.0 - Ardop doesn't launch at all. ("Exception:")
• Oct 27, 2021: Winlink moves from dotnet35sp1 to dotnet46
• Winlink 1.6.6.0 - Bug is present.
• Winlink 1.7.0.0 -
• Winlink 1.7.4.0 -
• Winlink 1.7.15.0 - Bug is present. _Using an old ARDOP exe (v1.0.2.5 from 2019) with a new Winlink Express (v1.7.15.0 from 2024) displays the same behavior as using a new ARDOP exe (v1.0.2.6 from 2024) with the same Winlink Express._

When ARDOP_Win.exe v1.0.2.5 is run on its own (instead of through Winlink Express / RMS Express.exe) we can play with the ARDOP settings menu more easily (Winlink Express won't keep restarting the program after 10 seconds of no audio). We can see that no sound card devices appear in the Capture or Playback areas.

ARDOP generates some of its own logs. Its exceptions log seems to indicate the main issue could be Method not found: void Microsoft.DirectX.DirectSound.DeviceInformation..ctor()

I realized Microsoft.DirectX.DirectSound might be a missing winemono method or maybe even a missing DLL - google took me to this Microsoft MSDN page which led me to Microsoft.DirectX.DirectSound.dll. I found that Austin English had already tracked this DLL to DXd21c and created a winetricks verb: winetricks mdx

Installing winetricks -q mdx fixed the soundcard detection issue. I was then able to successfully play tones through ARDOP.

dotnet46 install is not really feasible on most Pi systems since its installer is so unstable. Winemono is much more feasible to install and also MUCH faster to install and run software.

Fixed RMS Express + winemono + ARDOP by adding winetricks -q mdx 3e5c27fa2d764cedeeda38b156a6efdd6c4aa71f
