Hi all, Earlier last week I converted a Chromebook running ChromeOS to Debian Testing. Mostly everything runs fine out of the box and after some fiddling I got audio playing also working. However, the microphone does not work. Or, better worded, it picks up only noise when recording from it. I've used alsamixer to turn up some gauges and in GNOME I see the meter getting out of its corner, but when recording from the mike just noise can be heard. Has someone maybe a solution for this Acer Chromebook 15 CB3-532 or can point me out where I should look in the configuration for solutions? I've been away from Linux on the desktop for quite sometime (multiple SBC's and a NAS are running Linux here at home, but only as a server so no graphical user interface etc), you now have got things like Alsa UCM and PipeWire, which I'm not too familiar with. I hope to make this notebook my daily driver, also for work, but it would be cool if the microphone should work, as I have multiple online meetings a day... :-) Thank you for your help. I have here the output of alsa-info.sh, may this helps. upload=true&script=true&cardinfo= !!################################ !!ALSA Information Script v 0.5.0 !!################################
