cannot start pulseaudio daemon after adjusting libGL.so.1 settings for skype

[fINTiP]

http://askubuntu.com/questions/648069/if-i-fix-skype-according-to-another-au-thread-my-systems-sound-breaks-on-resta

Installing skype from the partner repositories. Try to start Skype. It fails. Search online. Found someone else with same error message.

Follow instructions in first answer with similar error reported in console. This was what I typed:

update-alternatives --display i386-linux-gnu_gl_conf

sudo update-alternatives --config i386-linux-gnu_gl_conf

(switched to /usr/lib/i386-linux-gnu/mesa/ld.so.conf (option "1") from these options:

` Selection Path Priority Status
------------------------------------------------------------
  0 /usr/lib/nvidia-304-updates/alt_ld.so.conf 9701 auto mode
* 1 /usr/lib/i386-linux-gnu/mesa/ld.so.conf 500 manual mode
  2 /usr/lib/nvidia-304-updates/alt_ld.so.conf 9701 manual mode
`

then ran `sudo ldconfig`.

Fixes skype issues! Sound works, skype works.

Later:

Restart computer.

Damn. No ability to adjust sound through pulse, only through alsamixer... the sound icon in the top right is greyed out, and system settings sound stuff has no effect... and, on top of that, skype sound is broken for playback, as well (though it does at least start, which is did not do before I used the AU fix listed above).

ps aux | grep pulseaudio returns nothing, and pulseaudio -D doesn't work

Anyone able to explain what's going on?

output from running pulseaudio:

E: [pulseaudio] ltdl-bind-now.c: Failed to open module /usr/lib/pulse-6.0/modules/module-bluetooth-policy.so: /usr/lib/pulse-6.0/modules/module-bluetooth-policy.so: wrong ELF class: ELFCLASS64
E: [pulseaudio] module.c: Failed to open module "module-bluetooth-policy".
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.

The bluetooth is a red herring, I have that intentionally disabled on restart. That has not broken the sound before, it wasn't until skype that it broke.

noticed that 'additional drivers' had me set to nvidia proprietary driver now, so tried to change that back to X.org Nouveau... That was hard, it wouldn't let me (I would restart and it would be right back on nvidia). Finally it let me be on nouveau. But I had installed and setup bumblebee previously... Maybe that's the source of my problem? But sound used to work on nouveau, even... So frustrating...

Have also tried purging pulseaudio from instructions on another ubuntu answer, then reinstalling. Now this is what I see:

kajo@kajo-Latitude-E6530:~$ pulseaudio
E: [pulseaudio] main.c: Daemon startup without any loaded modules, refusing to work.

:(

This was me listing the same bug with verbose alsa output, instead, before I realized it was pulseaudio. I ended up reinstalling at the time because I got an SSD. I had gotten the same problem after installing skype and going through the same solution, but at the time I didn't realize that skype was the cause. It was marked as answered, but it never was. (I went through that trouble shooting step this time, and it did not fix my issue):

UPDATE:

I finally just reinstalled, and thought based on other solutions in that same thread that installing skype before bumblebee might fix my issues. So, I reinstalled. Installed skype.

Skype works! Sound works! No config options even needed!

Restarted computer.

Pulse is broken.

Skype doesn't work.

Installed Bumblebee. Normally, this fixes my 'brightness' fn key functionality (which doesn't work out of the box on ubuntu, I think it's a nouveau bug). This time, it doesn't (including after a restart).

I try 'optirun skype', the command to run it under the nvidia card on bumblebee, according to yet another answer on that page. I get this output, suggesting, as I thought, that bumblebee isn't running:

    @:/etc/X11$ optirun skype
    [ 869.631200] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
    [ 869.631265] [ERROR]Could not connect to bumblebee daemon - is it running?

this is my log from nvidia:

    kajo@kajo-6530:~$ cat /var/log/Xorg.0.log | grep nvidia
    [ 6.225] (==) Matched nvidia as autoconfigured driver 0

    kajo@kajo-6530:~$ grep Driver /etc/X11/xorg.conf

I still kind of wonder if I install bumblebee first, but then use `optirun skype` for it, and don't change any system options, if I would be fine, but I'm loathe to reinstall my system yet again.
