systemd: oss.service - module-oss is deprecated

toni · 2013-05-11 09:09:02

I have installed oss4 and I have created an oss4.service as in arch wiki is said which contains the following lines:

[Unit]
Description=Open Sound System v4
Before=sound.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/sbin/soundon
ExecStop=/usr/sbin/soundoff

[Install]
WantedBy=multi-user.target

and systemctl status oss4.service is:

oss4.service - Open Sound System v4
   Loaded: loaded (/usr/lib/systemd/system/oss4.service; enabled)
   Active: active (exited) since sáb 2013-05-11 10:52:30 CEST; 10min ago
  Process: 435 ExecStart=/usr/sbin/soundon (code=exited, status=0/SUCCESS)

I have sound, and all seems to be ok, but for some reason in my /var/log/daemon.log there is an entry error saying:

systemd[1]: Cannot add dependency job for unit oss.service, ignoring: Unit oss.service failed to load: No such file or directory. See system logs and 'systemctl status oss.service' for details.

also dmesg is saying:

but I have check out /usr/lib/system.d/systemd/ folder and there is no such file oss.service, only oss4.service and ospd.service.
so how to uninstall module-oss and install new one module-alsa.card?

The output for systemctl status oss.service is:

oss.service
   Loaded: error (Reason: No such file or directory)
   Active: inactive (dead)

and for systemctl status ospd.service:

ospd.service
   Loaded: error (Reason: No such file or directory)
   Active: inactive (dead)

So how to solve the error entry that is appearing in daemon.log?

Thanks!

Ehm... Sounds like some other service is trying to load oss.service as a dependecy and fails as it is not there...

Do you by any chance have pulseaudio service enabled? Are you using pulseaudio at all? If not, disable/uninstall and it should go away.

I am not using pulseaudio, its daemon is not started, below output when I try to start it.

$pulseaudio --start
E: [pulseaudio] main.c: Daemon startup failed.

and if I execute pulseaudio:

$pulseaudio

E: [pulseaudio] module.c: Failed to open module "module-cork-music-on-phone": file not found

Below line error:

W: [pulseaudio] module.c: module-oss is deprecated: Please use module-alsa-card instead of module-oss!

is caused because in /etc/pulse/default.pa I have a line saying:

load-module module-oss device="/dev/dsp" sink_name=output source_name=input mmap=0

because in arch wiki, related to oss support, they suggested to have this line but as it is not working if I replace module-oss by module-alsa-card:

load-module module-alsa-card device="/dev/dsp" sink_name=output source_name=input mmap=0

pulseaudio output is:

E: [pulseaudio] module-alsa-card.c: Failed to parse module arguments
E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device="/dev/dsp" sink_name=output source_name=input mmap=0"): initialization failed.
E: [pulseaudio] main.c: Module load failed.

E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.

so, I comment line load-module module-alsa-card device="/dev/dsp" sink_name=output source_name=input mmap=0 and I put line load-module module-alsa-card in /etc/pulse/default.pa file, and pulseaudio outputs:

E: [pulseaudio] module-alsa-card.c: Card '0' doesn't exist: No such file or directory
E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: ""): initialization failed.
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.

Finally, I comment previous line load-module module-alsa-card in /etc/pulse/default.pa file, and I execute pulseaudio again, and its output is:

E: [pulseaudio] module.c: Failed to open module "module-cork-music-on-phone": file not found
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.

In my /etc/pulse/ folder there was a default.pa.pacnew so moved it into default.pa previously backing up my current default.pa file now pulseaudio can start.

but if I add below line again in /etc/pulse/default.pa:

load-module module-oss device="/dev/dsp" sink_name=output source_name=input mmap=0

adding mmap=0 for OSS support, below error is raised:

[pulseaudio] module.c: module-oss is deprecated: Please use module-alsa-card instead of module-oss!

so, why?

You get pulseaudio related OSS errors. I think you have it enabled by accident. A simple
systemctl disable pulseaudio.service (or something) should fix it. The error logs are consistent with failed pulseaudio start-up that you demonstrated.

I have not any pulseaudio.service in /usr/lib/systemd/system folder.

Something is starting the pulseaudio daemon in your user session (i.e., not systemd, something like KDE or GNOME I guess). If you are going to be using pulse, then you better use it with alsa, and not use OSS at all. Alternatively, make sure that you dont use pulse and you should be ok.

I prefer using OSS4 so how to remove pulse since I think gnome 3 is using it for something?

gnome-settings-daemon
lives
paprefs
pulseaudio-alsa

I am worried about gnome 3 stops working by uninstalling completely pulseaudio. How to remove completely alsa and pulse without affecting gnome 3 and OSS4?

Furthermore, how to stop below message to appear in the logs? => Cannot add dependency job for unit oss.service, ignoring: Unit oss.service failed to load: No such file or directory. See system logs and 'systemctl status oss.service' for details.

I have and oss4.service created in /usr/lib/systemd/system but not an oss.service.

Thanks.

Which oss package did you install? The package from the Community repo puts the oss.service file in /usr/lib/systemd/system. The wiki instructions about creating an oss4.service file are for the AUR package oss-hg.

Note that there is a new version of oss in Testing.

I had installed oss from community but I had some problems at linux startup: an annoying beep that started to sound and never stopped and after that I got to stop this annoying beep after a second (beep starts to sound and after a second it stops once configuration oss file is read). Some people told me to try oss-hg to solve this problem so I uninstalled oss from community and I installed oss-hg from AUR. This last is the one I have (anyway the annoying beep has not been solved - I have opened a thread as well related to this -).

I do not know if the new version of oss in Testing is correcting the beep issue. As I have read in other forums (http://www.opensound.com/) this issue is happening to more people, so I think it should be resolved, not sure If new version in testing is correcting this but it should be good.

Oss from community or oss-hg from AUR, the thing is that oss is causing me a lot of headaches. I think it should be improved a lot and it is not fully integrated in gnome 3.
For a moment I have thought in uninstall oss and install and use pulseaudio and alsa but I have maintained due to its high sound quality which uses a more precise algorithm.

Anyway as you say, arch wiki provides how to create a service (oss4.service) and I did. But for some reason something is raising oss.service and I have not any oss.service in my system and I have not installed oss, well oss-hg.

I want to stop that message to appear in my logs. Also, I have opened another thread related to the delay introduced by oss, both versions, community and AUR. See below:

I would like to solve all the problems I have related to oss, one is the annoying beep issue, another is the big delay introduced and also as said in arch wiki, add mmap=0 by doing the following to support OSS:

/etc/pulse/default.pa:

load-module module-oss device="/dev/dsp" sink_name=output source_name=input mmap=0

why below error is raised? Yes, I know module-oss is deprecated but how to achieve this now if mmap=0 is not supported?

[pulseaudio] module.c: module-oss is deprecated: Please use module-alsa-card instead of module-oss!

So maybe it is necessary to remove completely pulseaudio and alsa, and install again OSS.
So how to remove completely pulseaudio and alsa but without affecting gnome3? I think as I have said in the previous post that gnome 3 depends on pulseaudio.

Thanks.

Your oss4.service file is identical to the oss.service file except for the name. Maybe make a copy and name it oss.service and keep them both? What's the worst that could happen - Quadrophenia?

As I recall the best way to lobotomize pulseaudio is to uninstall alsa-plugins-pulseaudio. Other packages depend on pulse libs and alsa libs so you cannot remove those.

On my system oss4 takes ~59 seconds to start, at which time it spams the tty with two "...not known yet" messages. Maybe the new version will fix that.

nuc · 2013-05-16 01:17:07

Hi toni!
The issue that OSSv4 starts very long is described here https://bugs.archlinux.org/task/33969 (read the whole bugreport), although it is annoying quite annoying, it does not appear to do any harm apart from that.

Also http://www.opensound.com/forum/viewforu … 358ee8299d is a very good source of information. You might want to make a thread about your issue there, too, because the support is quite competent.
(As you've already stated) The beep issue is also addressed there.

What I do not really understand, is why you create your own systemd service file, because on my system it is already present. Also the HG repo was dropped in favor of GIT so it is not up2date anymore http://opensound.git.sourceforge.net/gi … ;a=summary
Anyways, there arent too many changes so I just recommend sticking to OSSv4 from Arch repos.

Hope you will be able to resolve your issues
