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

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

    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

    Hi,

    You could first check the group policy setting on the remote PC

    Local Computer Policy->Computer Configuration->Administrative Templates->Windows Components->Remote Desktop Session Host->Device and Resource Redirection

    Please ensure below two policies are enabled or not configured.

    Allow audio and video playback redirection
    Allow audio recording redirection

    And on the laptop, please enable below policy.

    Local Computer Policy->Computer Configuration->Administrative Templates->Windows Components->Remote Desktop Connection Client->RemoteFX USB Device Redirection-> Allow RDP redirection of other supported RemoteFX USB devices from this computer.

    As you described, the issue also maybe caused by the windows version. Since the version of laptop is higher than the remote desktop, then the remote desktop may have lower driver version, which cannot drive the laptop's microphone. Then the microphone fails to be redirected to the remote desktop.

    You can test to upgrade the windows of remote desktop.

    Please feel free to contact us if there is any update on your test.

    Thanks,
    Eleven
