I cannot adjust the volume properly because it would be mute or too loud even at 1%. I'm using a laptop with built in speakers of probably 4-6 internal speakers. I noticed that when using alsamixer+pipewire-pulse, there are PGA playback output controls that I can adjust and the volume controls works well on that, (especially on PGA1 and PGA30).

Other approach that I use is by changing the playback profile from HiFi quality music to Pro Audio can solve this problem temporarily but i have to manually reactivates this profile every time after suspending the laptop.

Does anyone have solution how to make the master volume, speaker volume respects the PGA1 and PGA30 playback slider?

For anyone wondering, this happens when the laptop has 4 speakers, my device is LENOVO Yoga Pro 7 14IRH8 and somehow it cannot controls the volume of the built in speaker properly (it can only mute and unmute even though we use the slider).

Current workaround is by configuring ["api.alsa.soft-mixer"] = true in /usr/share/wireplumber/main.lua.d/50-alsa-config.lua, source.

Or if you are using pipewire-media-session (defaults to 22.04 Ubuntu), you can try /usr/share/pipewire/media-session.d/alsa-monitor.conf and edit the api.alsa.soft-mixer = true

For those using WirePlumber 0.5 or newer, you will need SPA-JSON instead of Lua to enable soft mixer.

See https://wiki.archlinux.org/title/PipeWire#No_sound_from_USB_DAC_until_30.25_volume for an example config.
