-9999 Unanticipated host error by recording Windows 10 LTSC 2019

Audacity Help Forum Windows

Hello

I installed Audacity in version 2.3.2 on a Windows 10 LTSC 2019 notebook.
Soundcard is Realtek High-Definition Audio with latest driver.
Playback works.
When trying to start a recording I get an error message:
-9999 Unanticipated host error

I have already checked the known settings. The privacy option is set correctly. The sampling rate is identical to the driver setting.
All attempts with MME, WASAPI or Directsound did not bring any improvement.

In the Windows event log appears (German version):

Fehler beim Generieren des Aktivierungskontexts für “C:\Program Files (x86)\Audacity\audacity.exe”. Fehler in Manifest- oder Richtliniendatei “” in Zeile . Eine für die Anwendung erforderliche Komponentenversion steht in Konflikt mit einer anderen, bereits aktiven Komponentenversion. In Konflikt stehende Komponenten:. Komponente 1: C:\Windows\WinSxS\manifests\amd64_microsoft.windows.common-controls_6595b64144ccf1df_6.0.17763.737_none_05b6437c071e554b.manifest. Komponente 2: C:\Windows\WinSxS\manifests\x86_microsoft.windows.common-controls_6595b64144ccf1df_6.0.17763.737_none_4d637a531b9a7e51.manifest.

The method given at the end of this post to get more information with sxstrace only results in an empty logfile.

With e.g. Magix Video deLuxe you can record without any problems. So it can’t be the driver or the hardware.

Anyone else have an idea?

Are those drivers from the manufacturer of your computer, or are they the Microsoft Windows version, or are they the generic drivers from Realtek (or some other drivers)?

Not necessarily. Audacity uses high level calls to the sound system via PortAudio. This method is used so that Audacity can run on multiple platforms (Windows, Mac and Linux). A Windows only application such as Magix Video Deluxe may be using lower level API calls, (thus bypassing parts of the drivers) since it does not need to worry about supporting other systems.

Please post your “Audio device info”. (“Help Menu > Diagnostics > Audio device info”, then click “OK” to save the info as a file. Then attach the file to your reply: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1)

So it would appear that updating Audacity was not the problem.

Change the “host” setting back to “MME” in the Device Toolbar https://manual.audacityteam.org/man/device_toolbar.html

(The WASAPI setting is good for recording audio that is playing on the computer, but it also imposes restrictions on sample rates and some audio devices don’t support it properly. MME is generally a good choice in all other cases as it is supported by most device drivers)

Hello Steve,

In the old Version 2.1.2 direct after Windows 10 Update it works!

After Updating to 2.3.2 it don´t work. Deinstalling 2.3.2 and reinstalling 2.1.2 it also doesn´t work.

i have test all possible settings. MME, WASPI Direct Sound
Also the privacy Settings in Windows 10.

Nothing works.

regards
Andreas

At the moment you have a very complex setup. For trouble shooting purposes, we need to simplify so that we can narrow down the problem.

Does your computer have a built-in microphone?
