KDE Plasma 5 no sound

Hi,

first of all, I'm not sure if this belongs to "Desktop Environments" or "Multimedia", so please feel free to move this post.
My main problem is, that my fresh linux installation, using KDE Plasma 5 has no sound on my laptop with built in microphone and speaker.
As a first step, I installed "kde-multimedia-meta", "pulseaudio", "plasma-pa", "alsa-utils", "alsa-oss". I didn't futher configure any of these packages.
KDE Plasma sound utility lists a "Speaker" and "Digital Microphone" as unmuted.

Here's a few things I managed to find out:

soundcore                 16384   1   snd

So it looks like ALSA at least recognized the soundcard
Do I need to configure the system any further, or am I missing a module / package?

Re: KDE Plasma 5 no sound

Did you install pulseaudio-alsa ?

Re: KDE Plasma 5 no sound

Even though Plasma may list the outputs as unmuted, make sure to check that ALSA is Unmuted.

I did

amixer sset Master unmute
amixer sset Speaker unmute
amixer sset Headphone unmute

Funny enough, alsamixer only shows element "Master" (as unmuted). but an element "PCM" is not present. Might this be the problem?

Re: KDE Plasma 5 no sound

Short Update: I tested a bit further and somehow the headphone jack audio in + out seem to work. just not builtin microphone and speaker.
I'll update the information I got via the above listed commands (in original posts) soon.

Re: KDE Plasma 5 no sound

OK, so as promised my update. Sorry for taking so much time.
The current situation is now: I got audio in / out from the headphone jack, but not via builtin speakers and microphone.
The machine itself is a Lenovo Yoga 7i  with Win10 Dualboot (everything works under Win10).
However: When booting the machine with headphones plugged ine, one can occasionally hear an occasional cracking from the main speakers

I have the following packages installed

pacman -Q | grep "alsa"
alsa-card-profiles 1:0.3.20-1
alsa-lib 1.2.4-3
alsa-oss 1.1.8-3
alsa-plugins 1:1.2.2-2
alsa-topology-conf 1.2.4-2
alsa-ucm-conf 1.2.4-2
alsa-utils 1.2.4-2
pulseaudio-alsa 1:1.2.2-2
zita-alsa-pcmi 0.3.2-3

pacman -Q | grep "pulse"
libcanberra-pulse 0.30+2+gc0620e4-3
libpulse 14.2-2
pulseaudio 14.2-2
pulseaudio-alsa 1:1.2.2-2
pulseaudio-ctl 1.68-1
pulseaudio-qt 1.2-2
pulsemixer 1.5.1-2

pacman -Q | grep "firmware"
aic94xx-firmware 30-9
linux-firmware 20201218.646f159-1
sof-firmware 1.6.1-1
wd719x-firmware 1-7

However I didn't configure any of these packages further.
The kernel module vmd is loaded as an extra (machine would not boot without it due to "Grub: UUID not found").
/etc/modprobe.d/blacklist.conf  is empty (I did not edit it).
ALSA lists the following:

aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
samplerate
    Rate Converter Plugin Using Samplerate Library
speexrate
    Rate Converter Plugin Using Speex Resampler
jack

oss
    Open Sound System
pulse
    PulseAudio Sound Server
speex
    Plugin using Speex DSP (resample, agc, denoise, echo, dereverb)
upmix
    Plugin for channel upmix (4,6,8)
vdownmix
    Plugin for channel downmix (stereo) with a simple spacialization
default
    Default ALSA Output (currently PulseAudio Sound Server)
sysdefault:CARD=sofhdadsp
    sof-hda-dsp, 
    Default Audio Device
usbstream:CARD=sofhdadsp
    sof-hda-dsp
    USB Stream Output

Speaker-Tests gives me a "connection refused"

LC_ALL=C sudo speaker-test -c 8

speaker-test 1.2.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 8 channels
Using 16 octaves of pink noise
ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused

Playback open error: -111,Connection refused

Did I misconfigure something?
