Hello,
I have USB headphones that i passed to a VM and after some time sound disappears and then comes back after like 3 seconds(or doesn’t and i have to reboot windows ).
XML:
<hostdev mode="subsystem" type="usb" managed="yes">
<source>
<vendor id="0x1532"/>
<product id="0x0502"/>
</source>
<address type="usb" bus="0" port="6"/>
</hostdev>
Headphones has a built in mic. I tested the headphones on native windows and they work perfectly. I don’t know the exact model but it looks something like this link.
