Scenario
A room PC can display video through an adapter, but audio disappears after reboot until the adapter is replugged.
Recommended Resolution Path
- Check default playback device persistence and graphics driver health.
- Update dock, chipset, and adapter firmware if available.
- Test whether the issue follows one adapter model or one conference room image.
- Label the known-good port and adapter combination if the room setup is sensitive.
Technician Notes
Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
