I have a recently installed Parabola OS (basically Arch with OpenRC) on my Lenovo 3134A11, and since the beginning I have had no audio in the system. The thing is that when I run pavucontrol
, the window that opens freezes in "Establishing connection to PulseAudio. Please wait.", and trying any pactl
variants says "Connection refused".
Seeing this, I went to alsamixer
to see what's happening.
I put everything to the maximum and noticed that increasing-decreasing "Rear mic" with loopback enabled causes noise in the speaker.
So I think that means the system and Alsa recognize the driver;
but I still have no audio.
Here is some general info that I hope may help to illuminate the problem:

Hope that you guys can figure this out!
It's perfectly acceptable to add your answer as an actual answer, then mark it as accepted. Adding it at the bottom of the question & writing [solved] in the title isn't the way to do it. – Tetsujin – 2019-03-11T08:24:35.080
