Arch Linux. Sound doesn't work on H310M-K (chip Realtek ALC887-VD)
 

Help, please It's been 3 days I can't manage to get my jacks working on my motherboard H310M-K with audio chip Realtek ALC887-VD. For now I'm using the HDMI output on my graphics card but I need my speakers and microphone, please help. I'm using pulseaudio, I tried installing alsa and similar, I tried many things with pavucontrol but nothing, It's like the jacks are non existant, the system won't recognize them.

All of these might not be relevant to your machine, but they have info on the ALC887-VD.

Unfortunatley I already saw these and didn't help. Thanks for at least trying tho :)

Let's gather some basic info first - output of these commands please:

Output of aplay -l: https://pastebin.com/CEJYMUjL

Output of lspci -k|grep -A5 Audio: https://pastebin.com/wDKyLP1W

Output of cat /etc/*release*: https://pastebin.com/jRijbcj6

Ouput of uname -rmv:

I see no problem.
Does pavucontrol see the card (HDA Intel PCH)? Can you choose it as output device? What happens?
And what is this: "Extension [Sharkoon 7.1 Sound Extension], device 0: USB Audio [USB Audio]"? Digital headphones?

Ok, I've started experimenting more, and I saw that this doesn't work like with windows.
Sharkoon 7.1 Sound Extentions only works for the output jack when It's plugged in the frontal part of the pc, and the microphone only gets detected when it's plugged in the back of the pc. The microphone deosn't use sharkoon 7.1 sound extention tho.

I did not understand what you just wrote there.
Could you answer my questions please?
