Remote Desktop Connection not pulling in audio from local machine to remote physical machine

Michael Howard 41

Hello,

I am trying to pull in the microphone from a local machine (Win 10 1909) to a remote machine (a physical desktop-Win 10 1903). The microphone is an integrated mic in my laptop.
Remote Desktop connection settings: Play on this computer, record from this computer are both checked.
On the remote desktop, in Windows 10 settings, I see the remote audio is selected as output, but it has no input devices found.

With the same laptop and same settings as above I can remote into a VM (Win 10 1909) and I see remote audio is selected as output and remote audio is selected as input. The local (laptop) speakers and mic work fine on the remote machine as desired.

I have had the same issue with 2 other laptops/desktops (I not tried remoting into a VM to test that aspect)
Laptop (Win 10 1903) remoting into a Desktop (Win 10 1809)
Laptop (Win 10 1909) remoting into a Desktop (Win 10 1903)

I'm not sure if the issue is related to the version being one behind on the desktop(I will try to get at least one upgraded to test this weekend).

Any insights you can provide is appreciated.
Thank you,
Michael

I have the same issue, but am trying to access my work desktop (Windows) from my Mac laptop through the Microsoft Remote Desktop app (the orange one).

Remote audio is selected as output and input. When I try to change the volume levels, I can hear it. However, when I try to play or edit any kind of audiovisual content, there is no sound. How can I fix this?

Hi,

Thanks for your update.

Please check below registry for audio recording redirection. If there is no this registry, you could create a one. And set the policy to "not configured" to see the value of this registry, and then set to "enabled" to see the value.

If 0, audio recording redirection is enabled. If 1, audio recording redirection is disabled.

Registry Hive HKEY_LOCAL_MACHINE
Registry Path SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services
Value Name fDisableAudioCapture
Value Type REG_DWORD
Enabled Value 0
Disabled Value 1

Thanks,
Eleven

Okay I did some test with the registry value/local group policy.

Desktop (1909)
Group policy enable already had the registry entry of 0 - it works
Changed group policy to not configured the registry entry went away - it doesn't work
Left group policy not configured, added registry entry as 0 - it works

Desktop2 (1809)
Group policy not configured and had no registry entry - it doesn't work
Left group policy not configured, added registry entry as 0 - it works

VM
Group policy not configured and registry entry is not there - it works

So there got to be something odd going on with that VM. I won't be able to do any test tonight, but probably tomorrow night I will hop into other VMs to see if they have the same combo and if they work or not.

Thanks!

Hi,

Thanks for your test result.

Have you desktops joined any domain? How about your VM?

Thanks,

Hello,

Yes, they are all on the same domain in the same OU (We have GPO that apply to the entire OU). I went through the GPOs and couldn't find anything related to remote desktop being in them.

Thanks,
Michael

In that case, you might need to capture some dumps or traces to further investigate the issue, which I suggest to contact Microsoft Customer Support and Services where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue.

You may find phone number for your region accordingly from the link below:

Sorry for the delay. I remoted into two other VMs and they have the same settings, group policy not configured and registry entry not there. Both of them worked fine. I will look into contacting Microsoft Support, thank you.

Thank you for all of your help @Eleven Yu (Shanghai Wicresoft Co,.Ltd.) I will mark the registry edit as the answer, as that what fix my problem unless a recap would be better?

Yes that was the "Audio recording redirection was disabled by an administrator." part. But I'm not sure how it got disable on the physical machines and not the VMs (they are in the same OU with the same GP and go through the same setup process)

I found the problem "Allow audio recording redirection" in the local group policy was set to Not configured. I enabled it and now it works. I'm going to test it on the other PCs and see what it is set to on the VM tonight.

Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Sessions Host\Device and Resource Redirection

Thank you for all of your help @Eleven Yu (Shanghai Wicresoft Co,.Ltd.)

Edit:
The VM is set to not configured so I'm not sure why it was working there, but not on the physical machine.
