Lot of things showing in ALSA as 'Generic' usually suggests things are not quite right there

for ALC255 audio codec there is a kernel fix 'alc255-acer' listed:
kernel.org/hd-audio/alc22x-23x-25x-269-27x-28x-29x-and-vendor-specific-alc3xxx-models

to add kernel fix to system:

echo 'options snd_hda_intel model=alc255-acer' | sudo tee --append /etc/modprobe.d/alsa-base.conf > /dev/null

and reboot

That or a code box like so:

for a single line, or above and below for multiple lines.

this model laptop is known for quite a few issues on both windows and linux but in regards to linux this thread is mostly the same model as yours. maybe there's already audio issues mentioned and how to fix them?

nope, pulse works as intended, except for current KDE version where notification sounds are a bit off, but that's another story. Also, @andrewpintado, grab a nearest windows 10 disk and update your bios, 1.11 is pretty old and broken by "Today's standards"
