no audio devices - PulseAUDIO not started / crash / bug together with "pulseaudio multiband eq"?

[Mikael Thurberg]

Hi everyone!

Dont know what is wrong, but suddenly I have no sound..

have checked with "aplay -l " and it says it discovered both my graphics card audio (amd hd6450)
and the motherboard sound (intel alc260).. I run via intel sound this time..

But when I open the settings manager -> audio, it discovers no output devices at all
I can be able to change the sound to output via..

I have had this error 2 or 3 times before that the sound and the devices just "disappears", not sure why..
Dont remember if I did anything to get the sound back, after a while it started working again (not sure why eighter).

I also run / autoload the "pulseaudio multiband eq" at startup.. maybe it interferes and crashes with pulseaudio and this is where it all collides? I dont know..

I can run the alsamixer and everything seems to be working fine there, no problems with the mixer there, everything is discovered and changeable.

When I filed this bug, it said the pulseaudio had crashed.

When I run in command prompt this: "pulseaudio", I get as a response:

E: [pulseaudio] module-ladspa-sink.c: Master sink not found
E: [pulseaudio] module.c: Failed to load module "module-ladspa-sink" (argument: "sink_name=ladspa_output.mbeq_1197.mbeq master= plugin=mbeq_1197 label=mbeq control=-3.7,-2.3,-7.3,-8.9,-8.6,-6.9,-7.3,-6.3,-7.6,-8.9,-10.9,-9.2,-9.9,-12.9,-13.2"): initialization failed.
E: [pulseaudio] main.c: Module load failed.

Hope this could be of any help..

Thanks for reading!
Have a great day!

If it could help you save some time about this line as posted above:

"control=-3.7,-2.3,-7.3,-8.9,-8.6,-6.9,-7.3,-6.3,-7.6,-8.9,-10.9,-9.2,-9.9,-12.9,-13.2""

That are actually the settings in the Pulseaudio Multiband EQ that I have.. its how the different eq-sliders are set in dB if anyone wondered what that is.. now I probably saved someone eventually some time not having to check that up..

Have a great day!

update:

I did run the command:

"pavucontrol"

..but it didnt start / work..

I managed to fix it by running the following command:

"rm -r ~/.config/pulse; pulseaudio -k"

Then it did work, I started pulseaudio multiband eq again, but all my personal settings had gone except the default ones that came with pulseaudio multiband eq.. had to dial it in again.. no big deal.

Wrote everything down here if anyone will encounter a similar problem with using pulseaudio together with "pulseaudio multiband eq" if it would anyone!

Take care!

Its strange pulseaudio multiband equalizer could stop pulseaudio from not working at all..

well well.. its working now anyway, thanks for reading.
