 Posted: Sat Nov 06, 2021 4:13 pm Post subject: Inadvertently installed pipewire, now sound gone...! |
 |
|
On my foray back into linux on the desktop I decided I needed to use Gnome again. So switched (SDDM) into Gnome. Got scared (where's the familiar Gnome that I used to use ten years ago...). Switched back to XFCE but now my sound has gone.
I then find there's a new daemon running called pipewire? What on earth is this...  I did not worry too much,. but then found my sound has gone. Reset Pulseaudio but no help. Pavucontrol shows there's no output devices.
Turns out installing Gnome installed Pipewire and added a start file to SDDM.
So questions:
- Should I persevere with Pipewire and get it working? Is this the future of Linux audio (like PA, JACK, ALSA, OSS.....!).
or
- Should I trash Pipewire?
Thanks.
Cheers
Ferg

I removed the XDG autostart file for pipewire and now my sound has returned.
I'm still interested in whether people think it's a good idea to persevere with Pipewire or not?
Thanks.

To get sound to work, you need to stop pulseaudio (see https://wiki.gentoo.org/wiki/PipeWire#Replacing_PulseAudio).
Pipewire has a plugin that replaces pulseaudio, only one can be running at the time.
Pipewire is the "new" sound architecture, supposed to be a drop in replacement for pulseaudio, jack, and others. Also has a component to be a drop in replacement for several video programs.
Pipewire is being integrated into more programs (Firefox I think uses it by default), and it works as a pulseaudio replacement, but the other features are still in flux.
To answer your question about keeping it or not, your choice, but it appears to be a better version of pulseaudio at the moment. |

Thanks. Looks like I need to get with the times and configure Pipewire!

Whoops! So I removed the pulseaudio useflag and added the pipewire one.
Serious package blockage ensued.
So I tried to manually removed the pulseaudio package..!
Even more blockage ensued...! So then I thought why not just keep pulseaudio and pipewire emerged but just only run one..!
Too late....! I now cannot emerge pulseadio as the alsa plugins are blocking them (which appear to be needed).
Eeeek!
(this is a humorous post. I'm sure I'll fix it, but I was not expecting this!).

Pastebin your emerge output when the blockages happen.

Don't do that. pipewire acts as a drop-in replacement for PA and if you drop that support from packages, pipewire has nothing to drop in for. |

Thanks for that. I'll work on keeping both useflags.

Here you go. This is with both the Pipewire and Pulseaudio useflags set.

Many thanks, it looks a bit complicated to me.

I might be a replacement one day, but if I read the wiki you link to then pipewire is still in heavy development, can change a lot between minor versions, and generally is not yet ready. So I would not change a working audio setup with it until this can work flawless in RT.

Bearing that in mind it does seem curious to me why the Gnome Desktop profile adds the pipewire useflag. I never knew that I was installing Pipewire on emerging Gnome until audio stopped working...!

I came across a recent bug report where developers are discussing how Pipewire can coexist alongside Pulseaudio.
This suggests a new PulseAudio useflag called daemon. If you disable it then it allows Pipewire to take its place.
So if I do this I no longer have Pipewire and alsa-plugins blocking each other:
| Code: | | media-sound/pulseaudio abi_x86_32 -daemon |
But instead I get a fairly messy unsatisfied requirement error:
| Code: | !!! The ebuild selected to satisfy "media-sound/pulseaudio[abi_x86_32]" has unmet requirements.
- media-sound/pulseaudio-15.0-r1::gentoo USE="X alsa alsa-plugin asyncns bluetooth dbus elogind equalizer gdbm glib gstreamer gtk ipv6 orc sox ssl udev webrtc-aec zeroconf -daemon -doc -jack -lirc -native-headset -ofono-headset (-oss) (-selinux) (-system-wide) -systemd -tcpd -test" ABI_X86="32 (64) (-x32)"
The following REQUIRED_USE flag constraints are unsatisfied:
!daemon? ( !alsa !alsa-plugin !bluetooth !equalizer !gdbm !gstreamer !gtk !orc !sox !ssl !udev !webrtc-aec !zeroconf )
The above constraints are a subset of the following complete expression:
alsa-plugin? ( alsa ) bluetooth? ( dbus ) daemon? ( at-most-one-of ( elogind systemd ) ) !daemon? ( !alsa !alsa-plugin !bluetooth !equalizer !gdbm !gstreamer !gtk !jack !lirc !native-headset !ofono-headset !orc !oss !sox !ssl !system-wide !udev !webrtc-aec !zeroconf ) equalizer? ( dbus ) native-headset? ( bluetooth ) ofono-headset? ( bluetooth ) udev? ( any-of ( alsa oss ) ) zeroconf? ( dbus )
(dependency required by "@esteam" [set])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument]) |
TBH I've never been that good at working these out.

This tells you that if daemon use flag is not set, you have to unset all the use flags in the parentheses. |

Something like this will leave enough of Pulseaudio behind that applications can link against
| Code: | media-sound/pulseaudio -gconf -daemon -alsa -alsa-plugin -gdbm -gtk -udev -orc -ssl -webrtc-aec -X -elogind -asyncns -gstreamer

Thank you. I also had to add a few more useflags, but that got me past that stage.
| Code: | | media-sound/pulseaudio abi_x86_32 -bluetooth -equalizer -sox -zeroconf -gconf -daemon -alsa -alsa-plugin -gdbm -gtk -udev -orc -ssl -webrtc-aec -X -elogind -asyncns -gstreamer |
However, I'm back in blocking packages stage.
The crucial bit is this:
| Code: | * Error: The above package list contains packages which cannot be
* installed at the same time on the same system.

For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):

But the full log is here
Many thanks for everybody's assistance in my rabbit hole!

Ahh panic over. I had "alsa-plugins" in my /var/lib/portage/world file and that was causing it to be pulled in and blocking everything.
I removed that and world is now emerging.
Thanks again.
