Hi! I just want to chime in and document my workaround to use a generic UVC webcam with a built-in mic.
I attach a screenshot showing both a "multichannel input" and "microphone" once the UVC webcam is attached. Notice the picklist still does not contain an item for the system built- in [analog] microphone. ** Attachment added: "Sound setting missing picklist item for internal analog mic" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1866444/+attachment/5399088/+files/Settings%20-%20Sounds%20-%20Microphone%20-%20Camera.png -- 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/1866444 Title: [MacBook2,1, SigmaTel STAC9221 A1, Mic, Internal] Recording problem Status in alsa-driver package in Ubuntu: New Bug description: What you expected to happen Settings -> Sound -> Input to list internal mic (to test orange bars for recording from internal mic) What actually happened Settings -> Sound -> Input only lists "Digital Input (S/PDIF)" (no bars move because no digital input connected) If possible, a minimal series of steps necessary to make it happen, where step 1 is "start the program" 1.
