[solved] Pulseaudio warning about module-rescue-streams

Hi,

After last Pulseaudio update module-rescue-streams became deprecated and for this reason I'm seeing the following message in my logs when booting:

pulseaudio[775]: module-rescue-stream is obsolete and should no longer be loaded. Please remove it from your configuration.

However,  I cannot find that line in my configuration.

Could it be related to alsa-restore service?

Another possbility would be to delete all .tdb files and cookie in ~/.config/pulse because maybe some previous state is messing up things...

Re: [solved] Pulseaudio warning about module-rescue-streams

I'd say old tdb file config is more likely to be the issue here. alsa-restore is irrelevant to this.

Do you use anything that might implicitly try to make use of this? E.g. a specific volume mixer application/paprefs or so?

Re: [solved] Pulseaudio warning about module-rescue-streams

Not that I can remember besides having pavucontrol-qt installed. As far as I know it's only a frontend and I don't think it's loaded on boot or something. Anyway I haven't used it for a while.

I'm going to delete all tdb files and cookie and see. Didn't change anything...

Re: [solved] Pulseaudio warning about module-rescue-streams

I have the same error in my logs, I also can't figure out how to remove it.

Re: [solved] Pulseaudio warning about module-rescue-streams

Don't know if I could help but I have the option in my old config /etc/pulseaudio :

diff default.pa default.pa.pacnew
105,108d104
< ### Automatically move streams to the default sink if the sink they are
< ### connected to dies, similar for sources
< load-module module-rescue-streams
< 
143,146d138
< 
< ### Switch on connect
< load-module module-switch-on-connect
< 

and here as well :

diff daemon.conf daemon.conf.pacnew
57c57,58
< ; enable-lfe-remixing = no
---
> ; remixing-produce-lfe = no
> ; remixing-consume-lfe = no
60,61c61,63
< flat-volumes = yes 
< ; flat-volumes = yes
---
> ; flat-volumes = no
> 
> ; rescue-streams = yes

< 

As you can see for yourself I don't have that specific line in my default.pa neither module-switch-on-connect. According to Pulseaudio docs, latter module is way too agressive so it's not usually enabled by default.

I do have in daemon.conf:

; rescue-streams = yes

To my knowledge this is just the default value, which makes sense because from now on stream rescue feature has been moved to Pulseaudio core.

Re: [solved] Pulseaudio warning about module-rescue-streams

Check the contents of /var/lib/gdm/.config/pulse/default.pa if you use gdm - removing the load-module module-rescue-streams there fixes the error message.

Re: [solved] Pulseaudio warning about module-rescue-streams

same here:

pulseaudio[1496]: module-rescue-stream is obsolete and should no longer be loaded. Please remove it from your configuration.

using cadence & jack2 ... it seems to be an issue w/ the cadence package which still includes the load-module module-rescue-streams:

/usr/share/cadence/pulse2loopback/play+rec.pa
/usr/share/cadence/pulse2jack/play+rec.pa
/usr/share/cadence/pulse2loopback/play.pa
/usr/share/cadence/pulse2jack/play.pa

You've hit the nail @cluster. Problem solved

Thanks!

Re: [solved] Pulseaudio warning about module-rescue-streams

I do not know if it is right to intervene in a [Solved] thread. I have the same error but I don't have Cadence.
I solved it by commenting the "load module-rescue-streams" entry in:

/home/USER/.config/pulse/default.pa
/home/USER/.config/pulse/system.pa

I followed the suggestion of shihjay2 and the error messages ceased!  Like you, I don't have Cadence.  I actually don't have default.pa nor system.pa in the user .config/pulse/ folder.  Try the recommendation of shihjay2 if you haven't already done so.

Re: [solved] Pulseaudio warning about module-rescue-streams

Yes, I tried the shihjay2 solution, but I don't have the /var/lib/gdm folder.

Re: [solved] Pulseaudio warning about module-rescue-streams

module-rescue-streams is deprecated, functionality moved to the core

module-rescue-stream doesn't do anything any more, and is deprecated. When a device is removed, the module used to move streams on that device to some other device, but that is now handled by the core, so the module has nothing to do. If you have custom configuration that loads module-rescue-streams, you should remove the module from the configuration. Having it in the configuration doesn't do harm, but there will be warnings in the PulseAudio log.

Wonder if this needs to be reported upstream to GDM? Based on the release notes from PulseAudio quoted above, doesn't look like it will do any harm really.

Edit: Actually, nvm, ninjaed already by GDM 3.38.1-2

Re: [solved] Pulseaudio warning about module-rescue-streams

I updated to pulseaudio 13.99.2+13+g7f4d7fcf5-1 today from [extra] upstream and the issue has disappeared from my machine.

Re: [solved] Pulseaudio warning about module-rescue-streams

To everybody who does not have /var/lib/gdm or ~/.config/pulse:

Just look at /etc/pulse if there is a default.pa file to be checked.
