Bug 10343

vlc error popup

Some followup.

This affects only vlc.  Videos played under firefox are fine.

Googling shows that this problem is pretty widespread, but all the posts marked "SOLVED" involve uninstalling pulseaudio and forcing the use of alsa.  It also seems to be related to vlc 2.0 versus 1.13, with claims that a lot of plugins for 1.13 didn't make it to 2.0.  Possibly we have a missing requires on vlc for pulse systems ?

Hi Franks,

does this also happen to you with draksound configured not to use pulseaudio (which I always do)? Furthermore, can you try it in a new UNIX user account? (i.e add a new user, and login as it)?

Hi Frank,

here's what I found:

1. After I enabled Pulseaudio, then if I logged in in tty3 as my credentialys, and typed startx, then sound in VLC is working.

2. If I did "systemctl start prefdm.service" and logged in using that, then sound also worked.

3. Sound *did not* work in VLC if I typed "kdm" from a root console and logged in using that. I got an error in the console and when googling it found an Arch Linux bug report about it.

4. mplayer fell back on the OSS sound.

If I tried from an ID other than mine which had previously been used, I did not get the popup, but neither did I get any sound in either VLC or Kaffeine.  DragonPlayer worked.

If I tried from an ID which had never previously been logged on, everything worked.

I only get the popup, though, on my own ID.  However, DragonPlayer gives sound under my ID as well.

I get these results with either GDM or KDM.

By "If I tried" you mean "When I tried", right?

If so, then this is likely a local user configuration problem. You can try inspecting the output of «strace -f -o vlc.strace vlc» (without the « and ») to see where the problem is.

OK. Dragonplayer may be using the OSS interface. What does mplayer from the commandline with a path to the file give you?

OK.

Quite so :-)

Nothing really jumps out at me from the strace, except that a fork to run "/usr/bin/pulseaudio --start --log-target=syslog" completes with RC 1.

I tried running this from the command line standalone, and also got RC 1.  So I tried running "/usr/bin/pulseaudio --start --log-target=(filename)", and (filename) contained:


W  [pulseaudio] sink.c: Default and alternate sample rates are the same.
E  [pulseaudio] socket-server.c: bind(): Address already in use

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

I tried renaming both ~/.config/pulse and ~/.config/vlc, but the popup persists.

No sound, with similar complaints to vlc but more detailed:

OK, this seems ominous. Just a question - do your users belong to the "audio" group? What does «grep -P '^audio:' /etc/group» from the command line say?

Arggh.  I'd gotten used to replying to the bugs mail, and forgot there was actually a bug for this.  My last response didn't connect here, so here 'tis:

They don't, but they never have (the only one in the audio group is mythtv).

However, now I'm getting a popup from KDE whenever a removable volume is recognized, presenting a list of devices that KDE wants to delete because they are no longer present, and the audio ones are in the list.

*****************

I'll attach the screenshot of the popup.

Do you get sound with VLC on LXDE and/or IceWM instead of the KDE 4 desktop?

No sound, but no popup either, on either LXDE or IceWM.

I forgot and responded to the ML again.  Here's the latest:

Ahh yes.

Maybe. It's not 100% conclusive tho'.

The typical issue with not being able to load that module is that
someone else is already listening on the /tmp/.esd-601/socket socket
(where 601 is your $UID)

Normally the only think listening here is PA itself (i.e. another
instance). So what would typically happen is that two PA deamons try to
startup at the same time (perhaps one via autospawn and another via XDG)
and the slightly slower one fails only when loading this module.

In that case it *should* be a harmless error that has no consequence,
but obviously it looks suspicious so we can't rule it out completely.

One thing to check is if the ESD socket folder/file is somehow now owned
by root rather than your user. You can also try commenting out the esd
module completely in the default.pa (it's pretty useless these days as
I'm not really sure of any important ESD client apps and, in fact, we
don't even ship a libesd anyway!). I should likely disable it by default
(kinda surprised I don't!)


AS a side note, the whole autospawn stuff isn't ideal. Suffice to say
I'll be *very* happy when we use systemd for the user session and we can
use it's socket based activation stuff and forget about the whole
autospawn stuff in PA itself. That should make things more robust (in
theory at least!).

Nope.  Everything in there is owned by the user.

There is no occurrence of "esd" in either /etc/pulse/default.pa or /etc/pulse/system.pa.

This is still happening in current cauldron.  I've deleted ~/.xine, ~.gstreamer*, ~/.cache/gstreamer*, and ~/.local/vlc, all without effect.

I also hooked the home directory up to a fresh install.  Still happens.

Not sure what fixed this; I'm guessing the new KDE.  But it is fixed, and the annoying KDE popups asking me if I want KDE to "forget" half my devices (including audio) which I was getting every time I loaded a DVD are gone as well.
