PulseAudio Equalizer Script

[Nonno Bassotto]

I solved it removing .pulse

[psyke83]

I tried it and lost my sound. Before enabling it, I had two entries under the tab "output" in the Pulseaudio preferences. One reads

RV620 Audio Device [Radeon HD 34xx Series] Digital Stereo HDMI
Stereo

and the other one I don't remember, but had "Analog" in it. The one with analog was the one selected.

Now I have the digital one and

Lapsda Plugin Multiband EQ on RV620 Audio Device [Radeon HD 34xx Series] Digital Stereo HDMI
Stereo

but I lost the analog entry.

Noone of the two available entries allows me to hear any sound whatsoever.

What can I do?

Run:

$ pulseaudio-equalizer debug

Attach the log so I can see.

You can then run the equalizer, choose "Reset to defaults" from the Advanced menu to get sound working again.

I attached the log. When I ran it, a dialog came up, saying:
pa_stream_writable_size() failed: Connection terminated

Good job thank you

Hey, great job.
I'm having some trouble in karmic with 7.1. when I play some mp3 on audacious, totem, any app, the subwoofer channel it's quiet but when I apply some settings on the pulseaudio equalizer the subwoofer starts output the sound of the center channel. I stop & start audacious and the sound works again without the subwoofer.

I like the subwoofer working with the mp3 but I have to "apply settings" in the equalizer for every app playing sound.

it's a odd behavior of the equalizer,¿sould the subwoofer had worked form the beginning or the subwoofer shouldn't be activated when I apply settings?

The equalizer employs *software* equalization by filtering audio through a LADSPA plugin. What the implications are for surround sound configurations/subwoofer setups, I don't know (simply as I don't own such hardware, and therefore cannot experiment).

It may be the case that the LADSPA plugin only supports 2-channel stereo output, I've never looked into the issue deeply. You may want to investigate the alternate equalizer (linked in my first post, but remember that this is not a support thread for it).

Heya, my audio skips and stutters when the equalizer is active. Pulse takes ~20% CPU when it's active. Is my hardware too old? It's a Pentium D 820 (2.8GHz). Sound card is SB Audigy 4 (not pro). Memory is 2 GB.

Otherwise good work. I have my ghetto 4.1 surround made from two sets of two decade year old computer speakers and the stock HP woofer, but eh. VLC's equalizer works fine by the way, I think equalizing all of Pulse is too much for my rig.

E: BOINC is causing a lot of the skipping. Suspending BOINC stops most of it, but it's still there when playing music with VLC or whatever. Setting a lower nice value for pulseaudio removes it completely, but it has to be pretty mean (-10), which I don't like doing, really. I think optimization is in order, or, as I said, my machine is too old. It is...uh...5 years old? Yeah, that sounds right.

awesome stuff man - works perfectly in Lucid

The package doesn't pull necessary gnome dependencies on Kubuntu.

$ pulseaudio-equalizer-gtk

Great work! Exactly what I was looking for.
Thank you.
