What bothers me is the fact that with git version the card is not detected properly (on oS 11.1). I missed this detail in my report just because I did not try alsaconf after the problem first occurred. That is, alsaconf does not show it in the list of cards. So I guess that the sound driver uses some defaults (it does indicate the this is hda-intel) that just does not match the actual codec. While when I use stable 1.0.23 version card is detected by alsaconf and works correctly. >From the other side, the problem on oS 11.3 looks very different. I did not update driver there, just installed additional kernel that also has alsa 1.0.23. How it could lead to "Capture1" switch "reversing"? And now when I found it out and set it to "mute", Mic works correctly with recording SW and produces distorted audio in Skype in exactly the same configuration where it worked perfectly a couple of weeks ago.
