can't adjust volume

Asked by fINTiP

My sound used to work, not sure when/why it broke.

The weird thing is that my volume is not muted. It is stuck at a certain volume--pretty quiet, but audible. Hard to hear a phone call, though.

The volume applet next to the system clock in the top right is grayed out. My hardware volume buttons, which used to work, do not anymore. I have a Dell E6530.

When I click the applet icon, 'silentigi' is checked. (My system is in Esperanto; that should translate to 'to cause to be silent', so, mute?). But my computer isn't muted... I cannot uncheck it there. It shows the volume as 0%, and unadjustable.

When I click 'Sound Settings' under the applet dropdown menu, the volume looks to be at 0, and it has 'mute' checked, I think. I can adjust the volume here and uncheck 'mute'. It has no effect on my audio volume levels, however, no matter what I do. When I close the settings window and then reopen it, however, the volume is back down to 0, even if I had left it at a higher level. Mute stays unchecked, but again, it doesn't do anything either way.

Not sure what else to do.

This is the output I got from following the instructions at this page:

Maybe that's the source of my problem? I have no idea what to do with/about that, or if it's relevant, but the troubleshooting page suggested that if the version numbers don't match, one might have problems. It seems out of date, though.

In the pursuit of continued troubleshooting, I have now followed instructions found on the ubuntu wiki and installed the .deb on the following page: https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+sourcepub/5187168/+listing-archive-extra

I just restarted. Installing the previous package did not change anything about my problem.

However, I decided to try using 'alsamixer' in the terminal, and I can, there, adjust the volume by changing the 'master' setting.

Try:

killall pulseaudio; rm -r ~/.config/pulse* ~/.pulse*

Wait ten seconds then try some sound things. Can you change the volume OK?

A friend also advised that it was very likely pulse.

Looking some stuff up, I ran the following, and then noticed the following beneath it:

LANG=C pulseaudio -vvvv --log-time=1 > ~/pulseverbose.log 2>&1

( 0.028| 0.000) 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
( 0.028| 0.000) E: [pulseaudio] module.c: Failed to open module "module-bluetooth-policy".
( 0.028| 0.000) E: [pulseaudio] main.c: Module load failed.
( 0.028| 0.000) E: [pulseaudio] main.c: Failed to initialize daemon.

So then I did this:

:~sudo apt-get remove pulseaudio-module-bluetooth&1

And I think I restarted it with pulseaudio -D? Not sure. It made it work!

But then I rebooted my computer and it didn't work again. But killing and restarting the daemon seemed to make it work again!

I'll restart and run the command actionparsnip advised and restart again and get back to this thread.

Can you help with this problem?
