Sorry, I don’t use Pamac, won’t use Pamac, and truly believe there is a hex on Pamac, or should be, for all the trouble it causes. I’m not the only one here of that opinion. I only use Octopi or a terminal, or a clean chroot, (the best way) makepkg to install from the AUR. A terminal to uninstall packages.
And solely a terminal to update.
If I use Octopi in GNOME, which I do, I gussy it up with a utility pkg like adwaita-qt5 or whatever, so it looks like a GNOME app.
But back to Pamac. A lot of Arch-based (Garuda, Endeavour, etc.) users got burnt badly a couple of years ago and “once burnt, twice shy.” Pamac was originally written by a small team of Manjaro (a spin) users, and it was specific to Manjaro at that time. I remember telling them what a horrible, horrible play on our package manager “Pacman” it was, but oh well. 
They released it to the AUR, at some point it was poorly maintained, and broke everyone’s GRUB who used GRUB at that time. Hence the unpleasant odor it retains.
Some still swear by it. More swear at it.
I have no clue what your sound system problems are. Post a “garuda-inxi” output from your newly installed, updated, and rebooted Garuda here, so we have a fighting chance of seeing what’s going on.
I don’t use WINE at all; only rarely game with Steam. I only run Linux applications in Linux, and nearly all the same ported Linux/Windows or FOSS apps (firefox, onlyoffice, vlc, nordvpn, qbittorrent, bleachbit, maybe etcher, a few others)in Windows. If I ever run Windows again after today’s dust-up. I try to stick with what’s familiar. Except…
- Imagine my surprise to learn today that my /etc/udev/rules.d/60-ioschedulers.rules is most probably not needed (anymore) for Desktop Linux. Maybe a server or other specialized setup, but not mine. That, from a very knowledgeable Arch Forums moderator. Hunf! It’s still in the Arch Wiki’s Improving Performance section, though: Improving performance - ArchWiki And the example used is exactly what I use. Who knew?
