Only a small bit of static is audible at the start and end of recordings. - Family 17h/19h/1ah HD Audio Controller Stereo Microphone appears as inactive/unplugged. When headphones are plugged in, it becomes active and the headphone microphone works under that device. After downgrading to alsa-ucm-conf 1.2.13-2: - Both Family 17h/19h/1ah HD Audio Controller Internal Stereo Microphone and Family 17h/19h/1ah HD Audio Controller Digital Microphone appear as active recording devices without headphones plugged in. - Digital Microphone still does not record usable audio, only a small bit of static at the beginning and end. - Internal Stereo Microphone works correctly for the built-in mic when headphones are not plugged in. Plugging in headphones causes the headphone microphone to be used under the Internal Stereo Microphone device. Summary: The Digital Microphone is detected but never records usable audio. On 1.2.13-2, the Internal Stereo Microphone routes audio correctly from the built-in mic, so recording works, but the Digital Microphone itself remains nonfunctional. On 1.2.14+: - Digital Microphone appears but remains completely nonfunctional. - Stereo Microphone shows as inactive/unplugged until headphones are connected, making the internal microphone unusable. - Headphone microphone routing works correctly.
