Hi Sadeep,
This has likely nothing to do with pulseaudio/pipewire, but lacking linux support for your audio interface.
There are multiple MacBookPro's from 2017. Check which model you have:

And then check if that model has audio support under linux:

For 2017 models:
- MacBookPro14,1 (13", 2 ports): audio working with patch (only output)
- MacBookPro14,2 (13", 4 ports): audio not working
- MacBookPro14,3 (15"): audio working with patch I don't think that patch ever made it into the (arch) kernel, but I don't have my macbook anymore and haven't been following this for quite a while.

Hello,
I installed Arch Linux 6.11.1-arch1-1 on a 2017 Macbook Pro with KDE Plasma desktop package (initially installed the plasma-meta and kde-applications-meta, but I've since gotten rid of them). Sound output is not working with the speakers or headphones. KDE shows "No output or input devices found". During my troubleshoot, I ended up removingn pipewire stuff. Now I have pulseaudio, pulseaudio-alsa, and alsa-utils installed.
I created a file /etc/modprobe.d/50-sound.conf and added "options snd_hda_intel model=intel-mac-auto" to it (and restarted), but that did not help. I have installed alsa firmware and sof-firmware.

In alsamixer, Card shows as PulseAudio and the master volume is 100%. If I press F6 (to select sound card), the first entry is "- (default)". The second is "default:0 HDA Intel PCH". If I choose the second one, I see S/PDIF, S/PDIF 1, and S/PDIF 2. All of them are unmuted but the volume is 00. I can't increase it. The 00 is in a green square (not a rectangle up to 100%).
I can hear the chime when the Macbook starts up, so the hardware is working fine.
