Audio volume turned very low when sharing content via HDMI in MTR
The fix is coming in next MTR SW version.
You can use workaround to resolve issue: update Sound options - Communications - "Do Nothing"or set this regkey for skype user:
[HKEY_CURRENT_USER\Software\Microsoft\Multimedia\Audio]
"UserDuckingPreference"=dword:3
We have the same issue now with MTR 4.16.40 and Windows 10 IoT Enterprise 21H2
We use Poly devices, with HP for compute but aforementioned GC8 for consoles, but Poly support told us we have to reach out to Microsoft about this.
Registry UserDuckingPreference is already set to 3 for both Admin and Skype users, Communications - "Do Nothing" is checked separately for Admin user.
The experience is pertinent to all our new MTRs (they are mostly the same configuration).
Did anyone else experience the same issue with recent MTR versions? Any suggestions on how to fix?
Is there possibly a way to downgrade to stable 4.10.10.0 or 4.9.12.0. Older threads suggest it is not possible.
Also, I learned that there is a new, 4.16.134.0 (5/8/2023) - Manual update only MTR version. Would you advice to try it to solve our issue? And, if it turns out worse in some aspect, would we be able to revert, how?
