libasound_module_conf_pulse.so is missing from lib32asound-plugins

What version of Ubuntu are you using, and what application are you trying to use that requires 32-bit alsa?

 affects ubuntu/alsa-plugins
 status incomplete

Ubuntu 9.10, amd64.
When I run skype, it fails:

ALSA lib ../../src/conf.c:2700:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so
ALSA lib ../../../src/control/control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0
Aborted (core dumped)

After manually copy libasound_module_conf_pulse.so extracted from corresponding 32bit deb package to /usr/lib32/alsa-libs/, everything's ok.

I can confirm this... Skype will not start anymore, as of this morning's upgrade.

$ skype
ALSA lib ../../src/conf.c:2700:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so
ALSA lib ../../../src/control/control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0
Aborted (core dumped)

Details:

Ubuntu 9.10 Karmic Koala AMD64
Skype v. 2.0.0.72

I've tried adding libasound_module_conf_pulse.so to /usr/lib32/alsa-lib/ (not alsa-libs!), and the error doesn't go away. Maybe I am taking it from the wrong deb file?

Please list the installed versions of lib32asound2-plugins and ia32-libs.

Here's a fix that works for me (from http://mapopa.blogspot.com/2008/10/skype-2.html)

Create /etc/ld.so.conf.d/alsa32.conf with the following contents:

/usr/lib32/alsa-lib

After that, skype works fine.

> Please list the installed versions of lib32asound2-plugins and ia32-libs.

I am using the latest:

lib32asound2-plugins 1.0.20-1ubuntu4
ia32-libs 2.7ubuntu7

Right, I suspected as much. We probably want to revert the latest changes to
ia32-libs and alsa-plugins (in terms of the Replaces), because we cannot
build a 32-bit pulse alsa plugin on a 64-bit host due to there not being
lib32pulse*dev. In this case, we should drop lib32asound* from the
alsa-plugins source package.

I am using the latest:

lib32asound2-plugins 1.0.20-1ubuntu4
ia32-libs 2.7ubuntu7

-- libasound_module_conf_pulse.so is missing from lib32asound-plugins
https://bugs.launchpad.net/b...

The fix given by Truthiswithin did not work for me. I am using:

ii lib32asound2 1.0.20-3ubuntu2 shared library for ALSA applications (32 bit
ii lib32asound2-plugins 1.0.20-1ubuntu4 ALSA library additional plugins (32 bit)
ii ia32-libs 2.7ubuntu7 ia32 shared libraries for use on amd64 and i

Does anyone have any suggestions how to fix this?

You should first copy the 32bit .so file to /usr/lib32/alsa-libs/
and then use that fix.

I just found out I don't have a 32-bit so file. For example:

nasko@serre:~$ sudo updatedb
nasko@serre:~$ locate libasound_module_conf_pulse
/usr/lib/alsa-lib/libasound_module_conf_pulse.so
nasko@serre:~$ dpkg -S libasound_module_conf_pulse
libasound2-plugins: /usr/lib/alsa-lib/libasound_module_conf_pulse.so

Is this a regression in the 32-bit package?

lib32asound2-plugins did not (and does not) ship a corresponding pulse
alsa plugin for the simple fact that there is no lib32pulse* to build
against, so no, it is not a regression in that sense.

Thanks for the explanation. I tried copying the the necessary file from /usr/libs/alsa-lib to /usr/lib32/alsa-lib, but as expected this didn't work either. Is there a working fix for this issue?

The .so files in /usr/lib/ are 64bit libs, you have to download 32bit
package and extract the 32bit libs and copy them to /usr/lib32/alsa-libs/

Wouldn't the ideal solution be to build a lib32pulse package? What would that entail?

The solution would be to build a lib32pulse package, which is what will happen. However this is far from trivial.

I'm sure I don't understand the complexities of the lib32 packaging process,
but I know on my system just using the standard 32bit version of
libasound_module_conf_pulse.so works.

It *was* my belief that the lib32 libs are just repackaged builds of the
32bit libs. It sounds like that is not the case but considering it works,
why not do just that?

The plan is to get rid of this big piece of monolithic baggage that is ia32-libs. It will take a while, but if moving pulse to having lib32 packages helps with that process, then its well worth it.

Long term, there are much better plans for multi-architecture support, but these are probably a release or two away at least.

karmic amd64, skype-static here

I can confirm what Mingming and Oli wrote:
I took this file:
http://launchpadlibrarian.net/29924427/libasound2-plugins_1.0.20-1ubuntu6_i386.deb
unpacked the missing shared object files into /usr/lib32/alsa-lib/
et voilà... skype is running again

I have same problem, but copying that files did not help me. I am unable to run/hear sound from rhytmbox and flash video at same time.
When RBox is playing there is no sound in flash video or it even hangs and vice-versa :( No sound from RB until I close both applications :-/
Skype still closes with same error.
Any solution about this issue?

I tried copying files from the i386 package, to /usr/lib32/alsa-lib but this did not help. Skype no longer quits on startup, but when trying to call I get "audio device problem". I wonder if there is an alternative solution.

If you only want to get a working skype client give skype-static-oss a try. That one is independent from these libs..

Just copy the libs from the i386 deb package. You can use 'strace' to find out where it expects them to be.

For the long-term fix, I filed bug #414250 against pulseaudio.

I have just found a solution which works for my AMD 64 system and got skype working.

I extracted the libs folder from the deb file Raphael mentioned above with ARK and then copied the contents to /libs 32 under root.

It seems the standard reference to usr/libs32 is the wrong place for Karmic and AMD64.

I tried all of the mentioned solutions to no avail. I am able to run Skype without it crashing on me, but the program produces the following error:

bt_audio_service_open: connect() failed: Connection refused (111)

I'm sorry Rashad, but your problem is not covered by this bug.

This bug is about ALSA plugins not being available in 32 bit versions. In your case, it seems there is a misconfiguration or bug in the Bluetooth stack. You might want to open a separate bug for that, and try to reproduce the problem with an open-source application (that is, not Skype).

All the best,

What was the reason for libasound_module_conf_pulse being available 2 weeks ago? Skype did work back then.

2 Søren Holm, I think today I had this partial-dist-upgrade which replaced libasound2 packages so I guess until 2 weeks ago you have used older version of that package which included the libasound_module_conf_pulse.so.

Since today I had the same problem. Temporarily I've moved /usr/lib32/alsa-lib to /usr/lib32/alsa-lib.disabled and unpacked libasound2-plugins_1.0.20-1ubuntu6_i386 [http://launchpadlibrarian.net/29924427/libasound2-plugins_1.0.20-1ubuntu6_i386.deb] to be /usr/lib32/alsa-lib. Dirty solution but it seems to help.

I hope guys manage to build this 32 bit version including this libasound_module_conf_pulse.so as it will block all skype users until then.

I have noticed that in the past week (possibly just a few days) this has become significantly worse.

Before (with copied 32bit pulse libs) I could play 64bit applications could play directly through pulseaudio and 32bit apps could via alsa at the same time. Strangely this appears to also effect 64bit alsa applications too!

Now alsa appears to block native pulseaudio connections. Here are a few examples, all assuming I start with nothing playing on the audio server:
 - Example 1: If banshee is playing music (direct PA connection), Flash (64bit) has no sound.
 - Example 2: Flash is the only thing running on PA, works fine. I start totem and it has no sound. I have to terminate the Flash audio stream in pavucontrol to get totem's sound.
 - Example 3: Banshee is playing and something a dialogue makes a noise. The sound temporarily stutters the last note heard from Banshee. When the notification sound goes, banshee resumes as before.

I've no idea if this is *this* bug or a new regression... But it's really annoying.

The 64-bit Skype beta 2.1 solves this issue, indeed it solves a lot of problems with skype.

http://www.skype.com/intl/en/download/skype/linux/choose/

Yes, but it introduces another issue where it is not possible to select the audio sources. There is only "pulseaudio" to select from.

Changing package due to ia32-libs being where this needs fixing.

This bug was fixed in the package ia32-libs - 2.7ubuntu14

---------------
ia32-libs (2.7ubuntu14) karmic; urgency=low

  * Re-add libasound2-plugins (LP: #408615)
  * Remove libstdc++5, no longer in karmic
  * Freshen packages

@Soren, just to finish your comment, you can select input sources via Pulse Audio. I select between different microphones, for example. If you have any problem doing that, please open a bug against PA.

@Noel. Ok. pavucontrol did not work for though, so I just removed pulseaudio from my system falling back to alsa.

@mabawsa: Skype is not the only 32 bit app that needs to use ALSA. So this is not a solution.

There is a 64 bit version of Skype now.

Sorry, I found out that version 2.1 is still 32-bit, but there is now a
official 64-bit package (it contains a 32-bit binary :-( ).
