5 seconds of audio

I've got a laptop with

However since some kernel 4.8.x version I cannot record any sound - it records empty sound.

Any updates on this bug? Any information you might need from me? It's been two weeks since I filed it.

Another week with no microphone input.
Comment 6 Takashi Iwai 2017-02-28 16:26:50 UTC
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.

Where's the list of these quirks? How can the be applied?
Comment 8 Takashi Iwai 2017-02-28 16:50:47 UTC
Take a look at sound/pci/hda/patch_realtek.c.  There are lots of quirks, matching with PCI SSID.
Comment 9 Artem S. Tashkinov 2017-03-23 08:27:43 UTC
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.
Comment 10 Artem S. Tashkinov 2017-08-18 20:26:23 UTC
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.
Comment 11 Artem S. Tashkinov 2018-12-18 01:11:40 UTC
I've fully switched to PA, so let's close this bug report as it's no longer relevant.
