[opensuse-factory] [openSUSE:Leap:15.2, Build 617.1] pulseaudio and systemd vs. setup-pulseaudio
Hi there, this is on build ID 617.1. I use the script setup-pulseaudio sometimes to disable pulseaudio for a user session. This used to work without any trouble (on Leap 15.1 at least), but today I still found two processes running when logged in: "/usr/bin/pulseaudio --daemonize" and "/usr/lib/pulse/gconf-helper". And indeed, running "pavucontrol" doesn't hang/stop as it normally does when PA is disabled. As a consequence, Kodi refuses to switch to a non-PA audio setup, hence playing back some more enhanced video files and using audio passthrough is not possible. I don't want to discuss the issue with audio passthrough etc., but my main concern is "why does systemd always start up a pulseaudio daemon when logging in" - even when PA is disabled. To be honest, I don't know if this is a recent issue or if it existed in earlier builds, too, but I just realised it due to another issue with the 5.6 kernel not being able to do audio via HDMI anymore... Does anybody have an idea? Bugzilla? TIA, cheers. l8er manfred

Yeah, actually it's a fallout at transition to the user socket from the old autospawn invocation. It's a bit ugly but changing /usr/lib/systemd/user/pulseaudio.service like below should honor /etc/sysconfig/sound setup. OTOH, you should be able to disable the systemd user setup easily, too, so I'm hesitated for taking that... Takashi

The obvious question - why enabling/disabling socket is not done by setup-pulseaudio? If someone wants to disable PA, it I expect it also means stop activating it by socket, right? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

yes, that's what I have in mind, too. But anyway, thanks for the good hints to make it work again! Cheers. l8er manfred

[ -e /etc/systemd/system/pulseaudio.service ] && echo "already exists" || touch /etc/systemd/system/pulseaudio.service should be sufficient to disable it completely. Though the preferrable solution would be to fix up any issues with passtrough and pulseaudio, as in general that is supported, and would fix it for everyone else.

It's very close to the goal, but the working version is: ln -s /dev/null /etc/systemd/user/pulseaudio.service I'll update setup-pulseaudio script with that.

Come on, really. If you want to go this route (which is wrong) - spare /etc link and install your socket link in /usr/lib/systemd/user. Because /etc is not for packager to mess with - it is for end user. But the right thing is to enable or disable it in setup-pulseaudio, just like it has been working before.

"mask" is not intended as normal way to disable unit. "mask" is really last resort - if you need to use "mask", you likely have more general design issue. "mask" is really for units that cannot be enabled/diabled and are always active, and is more a debugging tool to troubleshoot or temporary work around a problem. It makes no sense to first unconditionally "enable" unit and then to conditionally "mask" it. Do not "enable" it in the first place, it is as simple as that. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Well, but for a user socket, mask (with --global option) would be the straightforward way, no? Takashi -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
