Any other had similar issue?
I'm using Lenovo ThinkSmart Hub, and when sharing content from my laptop via HDMI connected to MTR, volume level drops dramatically. No matter if I try increase volume from laptop or MTR or soundbar. Sound control panel communcation tab, "do nothing" has no effect.
Tested several Lenovo MTRs, all same. Have worked earlier fine. Teams Room client v 184.108.40.206

@Heikki_Kaukonen Same issue for our customers running same Teams app.
But for customers running a lower windows version, f.ex a 1909 build, no issue. Must be a combination of the latest win2h version and newest Teams app Client.

Talked to Logitech T3 support.
Its a bug in Windows 20H2. You need to reimage down to 1909.
A wide spred issue.

@frankiversen For a simpler fix to this issue, login as admin, open Control Panel, open Sound, click on Communications, then select "Do nothing". Click Apply.

I tried this solution on a Crestron Flex system - now the audio volume is at a much higher level over all, but there is still a noticeble drop in volume level when sharing via HDMI. @Michael Tressler

I've got the same problem on multiple systems, both Yealink and Crestron. Any updates on how to fix or work around? Were going to rollback but 10 days was pasted...:-(

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:

is there a release date for the next MTR SW Version?
i am new to MTR, only a few Test Systems in our Company so far.
But this is a killer to user experience.
never had such a heavy bug with the Cisco Rooms Systems in 5 years.
i tried the Setting with "do nothing" on 2 Poly G10-T Devices wich use Lenovo Thinksmart Hub as compute and GC8 as Touch and HDMI Ingest.
on both systems there was no volume problem anymore when sharing HDMI.
Did the Settings as admin and affected the Skype user also.

I wonder if anyone has experienced this issue again on 20H2 running MTR: 220.127.116.11 ?
I've since used Regedit to load in the hive from Skype user and see it has the Ducking reg DWORD already set to 3 so don't see this as a valid workaround for my client.

Not me, since the update the problem was gone for us. We run a lot of 18.104.22.168 now with 20H2
