I have media-plugins/alsa-plugins[-pulseaudio] installed. Each time I try to emerge media-video/pipewire[pipewire-alsa], I get

Looking at the ebuild, it looks like the intent is to make media-video/pipewire[pipewire-alsa] and media-plugins/alsa-plugins[pulseaudio] mutually exclusive. However, this is not what portage comes up with ... so there seems to be a logical issue in the implementation.
I've patched the ebuild (see attachement) to rather have !media-libs/alsa-plugins[${MULTILIB_USEDEP},pulseaudio]. This yields

	pipewire-alsa? (
	!pipewire-alsa? ( media-plugins/alsa-plugins[${MULTILIB_USEDEP},pulseaudio] )

Now portage happily emerges media-video/pipewire-0.3.28, see below. This might also help with bug #785076.

Comment 1 Niklāvs Koļesņikovs 2021-05-23 15:04:46 UTC
Assuming this still works as intended, I'm sorry for introducing this bug. As for MULTILIB_USEDEP there, it being set or not when blocking the PA plugin should not make a difference to PipeWire's functionality. The PW's ALSA plugins will be built and installed according to multilib USE flags for pipewire ebuild, and multilib'ing of other ALSA plugins is irrelevant. The only thing important is that PipeWire and PulseAudio plugins are not installed at the same time. If it was necessary for correct dependency resolution, that's fine, however.
Comment 2 Olivier Huber 2021-05-23 16:23:14 UTC
No worries, when I looked at the ebuild I guessed an intention and it seems that portage's dependency resolution algorithm sees it differently. I'm not an ebuild expert either.

The remaining question is whether the condition 

!pipewire-alsa? ( media-plugins/alsa-plugins[${MULTILIB_USEDEP},pulseaudio]

is necessary? In essence, if the pipewire-alsa useflag is not active, do we need to pull a dependency on media-plugins/alsa-plugins[${MULTILIB_USEDEP},pulseaudio] ?

From what I get, it is clear that if pipewire-alsa is enabled then media-plugins/alsa-plugins[-pulseaudio] is required. Is anything more required? If the user choose not to have pulseaudio-related functionalities at all, we might not want to force them on him/her?
Comment 3 Niklāvs Koļesņikovs 2021-05-23 21:20:55 UTC
That's just bug 785076 all over again and I expect the answer hasn't changed - Gentoo cares for decent out of the box experience and not someone's hate for ALSA or PulseAudio or (misguided) intentions to build a minimalist setup. Users are free to pursue them by using package.provided and other support voiding techniques but Gentoo as a project is under no obligation or intention of complicating ebuild logic or adding additional USE flags, or intentionally enabling known broken configurations just because someone feels entitled to that.
Comment 4 Olivier Huber 2021-05-24 09:10:31 UTC
So there is no technical argument for this dependency. The updated patch takes care of helping provide a good experience by having an IUSE default flag on pipewire-alsa

Sorry about that. The updated patch for 0.3.34 should be okay. Let me know if you run into any trouble.
Comment 9 Niklāvs Koļesņikovs 2021-09-02 13:05:02 UTC
Just as a quick reminder, media-plugins/alsa-plugins[${MULTILIB_USEDEP},pulseaudio] *does not* depend on or link against media-pulse/pulseaudio, so the dependency is very small and lightweight, therefore it's really unreasonably to object to just because it has pulseaudio in the USE flag. Meanwhile not having it installed will break the user experience for far more people than the number who care about having a system without the word pulseaudio anywhere in its filesystem.
Comment 10 Niklāvs Koļesņikovs 2021-09-02 13:12:11 UTC
Correction, I was kinda wondering about this, so I did a quick check and turns out I was wrong and it does link against PulseAudio, so while the plugin itself is still just a few average size C files, it does pull in pulseaudio (though it should compile against media-sound/pulseaudio[-daemon]). Is it really not good enough to just turn pipewire-alsa USE flag on and not care that by default it will pull in a package that pulls in PulseAudio?
