I have a fresh gentoo installation with plasma profile selected.
Before doing world update I had explicitly stated in make.conf "-pipewire"

I really don't want new things to be forced onto me like Windows

So plasma pulls in
Code:
media-sound/pulseaudio
package which shows
no files installed with
Code:
 equery d media-sound/pulseaudip
and it also installs
Code:
media-sound/pipewire
with
Code:
  sound-server
USE flag.

Either plasma itself did that or
Code:
 steam-launcher
did that. I doubt
steam pulled that out because most of the steam related USE flag changes are for 32-bit binaries of
specific packages. I can't say for sure.

Currently I can't set
Code:
 -sound-server

on
Code:
media-video/pipewire
because :
Code:

[ebuild   R    ] media-video/pipewire-1.0.5  USE="-sound-server*"

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

media-video/pipewire:0

  (media-video/pipewire-1.0.5:0/0.4::gentoo, ebuild scheduled for merge) USE="X bluetooth dbus readline ssl -doc -echo-cancel -extra -ffmpeg -flatpak -gsettings -gstreamer -ieee1394 -jack-client -jack-sdk -liblc3 -lv2 -man -modemmanager -pipewire-alsa -roc (-selinux) -sound-server (-system-service) -systemd -test -v4l -zeroconf" ABI_X86="(64) -32 (-x32)" pulled in by
    media-video/pipewire (Argument)

  (media-video/pipewire-1.0.5:0/0.4::gentoo, installed) USE="X bluetooth dbus readline sound-server ssl -doc -echo-cancel -extra -ffmpeg -flatpak -gsettings -gstreamer -ieee1394 -jack-client -jack-sdk -liblc3 -lv2 -man -modemmanager -pipewire-alsa -roc (-selinux) (-system-service) -systemd -test -v4l -zeroconf" ABI_X86="(64) -32 (-x32)" pulled in by
    media-video/pipewire[sound-server(+)] required by (media-libs/libpulse-17.0:0/0::gentoo, installed) USE="X asyncns dbus glib gtk -doc (-selinux) -systemd -test -valgrind" ABI_X86="32 (64) (-x32)"
                                                               


Now what is even libpulse???

And then I cannot depclean media-video/pipewire and someone suggested in other posts because :

Code:


Calculating dependencies... done!
  media-video/pipewire-1.0.5 pulled in by:
    media-libs/libpulse-17.0 requires media-video/pipewire[sound-server(+)]
    media-video/wireplumber-0.4.17-r1 requires >=media-video/pipewire-0.3.68:=, >=media-video/pipewire-0.3.68:0/0.4=
    sys-apps/xdg-desktop-portal-1.18.4 requires >=media-video/pipewire-0.3:=, >=media-video/pipewire-0.3:0/0.4=




I want pulseaudio with daemon and no pipewire. How do I fix this? [/b]

The plasma profile enables pipewire's USE=sound-server by default:

Yes but what is the solution?

I don't want pipewire, just want pulseaudio daemon and alsa, like before.


This does not work either: https://www.gentoo.org/support/news-items/2022-07-29-pipewire-sound-server.html

EDIT: Removed incorrect suggestion.

xgivolari understood the situation better than I did and gives the correct solution.
If it is any consolation to you, I switched (reluctantly) to pipewire when that news item came out. I have not had any major issues. The transition to pipewire has been in the works for some time. I finally learned to embrace it.

pulseaudio was split into multiple packages a while ago to make the transition to pipewire easier. the pipewire dependency of libpulse is as follows:
Code:
PDEPEND="
    || (
        media-video/pipewire[sound-server(+)]
        media-sound/pulseaudio-daemon
    )
"

This means that libpulse either depends on pipewire with sound-server enabled, or on pulseaudio-daemon, which is the pulseaudio subpackage that provides, well, the daemon. To replace pipewire with pulseaudio daemon, disable the sound-server USE-flag on pipewire and run "emerge --oneshot pipewire pulseaudio-daemon". This will rebuild pipewire without sound server support and pull in pulseaudio-daemon to satisfy libpulse's dependency.

Of course it is none of my business how you run your system, but I would strongly recommend to at least give pipewire a try. Standalone pulseaudio is more or less dead. Pretty much all other distros have replaced pulseaudio-daemon with pipewire as well. Unless you have any specific issue with it, pipewire is considered superior to pulseaudio in every way.

This should negate the pipewire +sound-server use flag enabled by your profile.
If that is correct, then you should be able to proceed with the setup of pulseaudio as instructed in the news item you referred to.
I think this is not the correct approach. If OP wants USE=-sound-server on pipewire, that should be done in package.use, not in profile/package.use.mask. I have no opinion on whether OP should disable USE=sound-server on pipewire. Per the post above mine, returning to pulseaudio may be a path to more work, not less.

That would forcibly enable the flag. Profile-defined defaults can be overwritten via make.conf or package.use, unless defined in a *.force or *.mask file.

I am using also a kde/plasma profile. This profile sets the use-flag "pipewire" as default. The correct file (or directory) is - like @Hu already explained - /etc/portage/package.use and the the use-flag "sound-server" must be disabled with a minus-sign: media-video/pipewire -sound-server as explained in our news from: "2022-07-29 PipeWire sound server migration"

Dont try to disable "pipewire" completely because KDE needs it anyway.

(In my case: I have a pure ALSA configuration: no pipewire and no pulse-audio and therefore I have in my make.conf: USE="-pulseaudio..." (but no -pipewire) and in my package.use above setting for deselecting the sound-server of pipewire)

You are correct. I will correct my original post.

I now have pulseaudio as server and no pipewire sound server but media-video/pipewire is installed.
Here's what I learned; correct me if I am wrong. pulseaudio has
Code:
 media-sound/pulseaudio
It installs nothing
Code:
 media-libs/libpulse
Installs client pulseaudio libraries
Code:
 media-sound/pulseaudio-daemon
This seems like pulse audio server. Then what is the use of
"daemon" USE flag in
Code:
 media-sound/pulseaudio
?

wine definitely media-sound/pipewire but not necessarily with sound-server.

For pulseaudio server and no pipewire sound server one has to install pulseaudio-daemon, pulseaudio and libpulse.

media-sound/pulseaudio is a transition package. media-sound/pulseaudio[daemon] depends on media-sound/pulseaudio-daemon, so that users will seamlessly migrate to the new package and not silently lose their sound daemon.
