Can you check if this doesn't fix your problem?

https://unix.stackexchange.com/questions/479058/audacity-doesnt-work-with-pulseaudio-anymore/479470#479470

It did for me. Also, I see that there is a new version of alsa-lib 1.1.7-2 (on my archlinux) but I haven't tested yet.

[D06E]

Just to clarify, I should try to downgrade my alsa-lib from 1.1.7 to 1.1.6?

[fabiofalci]

Yes, downgrade to alsa lib to 1.1.6.

[D06E]

Thanks for your help. It guess this works but I have not found a way to go back to 1.1.6 yet.

[fabiofalci]

What distro are you using?

[D06E]

Manjaro i3 Community Edition. It's a new install, so I don't have a previous alsa-lib file on my drive.

/var/cache/pacman/pkg/alsa-lib-1.1.6-1-x86_64.pkg.tar.xz <- that file is missing for me.

[fabiofalci]

Ok, I guess you need to build the package then. Something like this should do:

$ wget https://git.archlinux.org/svntogit/packages.git/snapshot/packages-0b0e7fc07cdc2bcf0b083dfbc38e4a7c484b2bc1.tar.gz
$ tar xvf packages-0b0e7fc07cdc2bcf0b083dfbc38e4a7c484b2bc1.tar.gz 
$ cd packages-0b0e7fc07cdc2bcf0b083dfbc38e4a7c484b2bc1/trunk/
$ makepkg -s
$ sudo pacman -U alsa-lib-1.1.6-1-x86_64.pkg.tar.xz

The file https://git.archlinux.org/svntogit/packages.git/snapshot/packages-0b0e7fc07cdc2bcf0b083dfbc38e4a7c484b2bc1.tar.gz is from the commit of 1.1.6 as you can see here https://git.archlinux.org/svntogit/packages.git/commit/trunk/PKGBUILD?h=packages/alsa-lib&id=0b0e7fc07cdc2bcf0b083dfbc38e4a7c484b2bc1

Again, thanks for the help! I was able to downgrade, but I still have no sound.
