Status changed from Fixed to Awaiting confirmationStatusFixed→Awaiting confirmation
This was closed in a bulk cleanup before Fluxer V2 without being checked or fixed. It may work now, so it is waiting for someone to confirm whether the bug still happens.
I believe you are misunderstanding what the string in parentheses represents.
Audio In/Out is handled by a dedicated sound chip, in your (and my) case that is a sound chip on the motherboard.
The "MAC address" you mentioned is a typical PCI ID you'd see on any other PC.
Your sound chip has a PCI ID assigned to it.
The IDs you see here are comprised of a Vendor ID and a Device ID, separated by a colon.
A sound chip may have multiple audio inputs and outputs, but they all belong to the same sound chip, all inheriting the same PCI ID.
P.S.:
MAC addresses are a networking thing. They live in OSI/ISO layer 2, aka the Data Link Layer.
