I just tested the kernel upgrade to 5.8.0-60-generic from focal-purposed
using aptitude. I see no changes at all all the issues remain don't
think the fix has been implemented yet.

Title:
Acer Aspire 5 sound driver issues
Status in linux package in Ubuntu:
New
Bug description:
Hello,
There seems to be lots of issues in sound driver for Acer Aspire
A515-56-57XR with ALC255. I will list all of them below and what I
have tried so far.
1. Headphones appears always plugged in even if they are physically not
2. When actually plugging in headset/earphones it does not auto switch from speakers/internal mic to headphones/headset microphone automatically and vice versa, have to manually switch everytime.
3. External headset/earphones microphone won't work at all
After, logs of trial and error I have found a temporary fix. This
seems to use legacy intel drivers which solves all 3 issues mentioned
above but the internal/dmic mic is completely gone (which seems
intentional when using this). Both depreciated dmic_detect and
dsp_driver works, I have been using dsp_driver for now as I need
external microphone at any cost.
End of /etc/modprobe.d/alsa-base.conf
# Headset mic fix
options snd-hda-intel dmic_detect=0 / options snd-intel-dspcfg dsp_driver=1
options snd-hda-intel model=alc255-acer
In another thread similar to this I got some support and at least
fixed the external microphone without using the alsa-base.conf change
in custom modified kernel. I will attach it here. Now, hoping to fix
other issues as well slowly like making headphones unplugged when
physically removing as well as auto switching like the legacy driver
one.
