USB Microphone - 4K Dual Monitor HDMI KVM Switch

Hello, I received my KVM switch and while installing it I had a particular problem.
Product : AV Access 2x1 4K Dual Monitor KVM Switch w/HDMI

I have a USB microphone plugged into the front panel of the switch (USB 3.0)

And I plugged my USB type B to type A on my PC 1 into a USB 3.0 port as well.

Same on PC 2

My microphone is detected on both machines, however on PC 1 no sound comes out of the microphone while it comes out well on PC 2.

My 2 PCs are under Windows.

PC 1 Motherboard:
-MSI B550-A PRO

PC 2:
-Dell Inspiron 7430

I checked the microphone configurations on my 2 machines but nothing I can do about it doesn’t work.

I have other peripherals connected (keyboard, mouse, etc.) no problem.

Thank you for your help.

Jules

Hello Jules,

Sorry about that, more tips that how about try switch the microphone to other USB 3.0 port in KVM,or all three ports same?
And could you try check and update the PC1 USB driver to have a check.
