[Bug 1881094] Re: Support kernel 5.4 Intel sound driver on bionic

[Łukasz Zemczak]

Hello Kai-Chuan, or anyone else affected,

Accepted pulseaudio into bionic-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/pulseaudio/1:11.1-1ubuntu7.9 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: pulseaudio (Ubuntu Bionic)
       Status: Triaged => Fix Committed

        Software & Updates > Developer Options > Pre-released updates (bionic-proposed)
