[Bug 1925057] Re: [82A1, Realtek ALC287, Speaker, Internal] Underruns, dropouts or crackling sound

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
[82A1, Realtek ALC287, Speaker, Internal] Underruns, dropouts or
crackling sound

Status in linux package in Ubuntu:
Fix Released

Bug description:
Hello,

I'm using Ubuntu together with Windows on my laptop.

If I boot in Ubuntu after Windows sound doesn't work well (instead of
system sounds I can hear only shot noise). To fix the issue I need to
completely shut down the system (call Power Off via Ubuntu GUI) and
then boot again in Ubuntu. Please note, that reboot (called via Ubuntu
GUI) doesn't help to fix the issue.

Expected result: sound works well regardless of boot history.
Actual result: every time I boot in Ubuntu after Windows sound doesn't work.

Issue occurrence: 100%.

Environment:
