Another week with no microphone input. Unfortunately, it's a thing only the hardware owner can figure out. Just do trial-and-error of some more model options or apply the quirk line manually that may match with yours. Pinging on the bugzilla won't help.

How can the be applied? Take a look at sound/pci/hda/patch_realtek.c. There are lots of quirks, matching with PCI SSID. patch_realtek.c weighs over 200KB and I don't think of myself as a programmer to understand how to work with this file to get the microphone back. Is there an utility to configure the HDA codec parameters in real time without recompilation? I remember you had something like that in the past. The plot thickens. I tried using PulseAudio for a change and it actually detected two inputs while `arecord -l` sees just one. And one of those two inputs actually work just fine. However when I run plain ALSA there are no controls to switch between different inputs. It seems like PulseAudio sees (and manages to control) something other mixer applications (alsamixer/xfce4-mixer) don't see. I'm utterly confused. Please tell me what I'm overlooking. I've fully switched to PA, so let's close this bug report as it's no longer relevant. |
