Check HP hardware manual says "When a device is plugged into the Microphone/Headphone Connector, a dialog box will pop up asking if you want to use the connector for a microphone Line-In device or a headphone. You can reconfigure the connector at any time by double-clicking the Audio Manager icon in the Windows taskbar."
So, i think this jack is not combinated. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1597708 Title: [HP EliteDesk 800 G1 DM, Realtek ALC221, Black Mic, Front] Duplex mac/headphone port does not produce sound.
