No sound, and kde doesn't detect soundcard

Hello there!

I recently installed arch on a handheld laptop, and my sound doesn`t seem to be working.

aplay -l shows this:

**** List of PLAYBACK Hardware Devices ****
card 0: chtrt5645 [chtrt5645], device 0: 1 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: chtrt5645 [chtrt5645], device 1: Deep-Buffer Audio (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Audio [Intel HDMI/DP LPE Audio], device 0: HdmiLpeAudio [Intel HDMI/DP LPE Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Audio [Intel HDMI/DP LPE Audio], device 1: HdmiLpeAudio [Intel HDMI/DP LPE Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Audio [Intel HDMI/DP LPE Audio], device 2: HdmiLpeAudio [Intel HDMI/DP LPE Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Which i guess means that my system did detect the soundcard, but for some reason it`s not working.

Any ideas as to why?

Did you unmute your card? Does speaker-test work?

I'm pretty sure KDE uses pulseaudio, but first make sure you can output audio without it using bare ALSA.

I can't find Master on neither of them, chtrt5645 has a lot of channels and I unmuted almost all of them in hope that they might work, on the other hand Intel HDMI/DP LPE Audio has only one channel but I cannot mute/unmute it, and it says <PCM>

Speaker-test isn't working, also after every

Time per period = 10.x

it says

0 - Unknown

Can you post

amixer -c0
sudo fuser -v /dev/snd/*
#Do any of these two produce sound?
speaker-test -Dhw:0,0 -c2
speaker-test -Dhw:0,1 -c2
