HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

[psyke83]

OK I'm not geting any sound following an upgrade from hardy to intrepid. I'll I get is static clicking noises when sound is playing.

I've followed the instructions in the opening post of this thread and everything seems the same.

Your PCM volume is muted/set to 0%. It's covered by Part C, Step 3.

[psyke83]

Thanks for the help!

So now it's mostly working, Exaile, Totem, VLC... they're all playing out of the SB Live! like I configured in Pulse.

Two things are still amiss:
1. For some reason Firefox (streaming sound and such) is still working out of the on-board card
2. The front panel and the card at the PCI work simultaneously instead of the former taking over once a headset is connected to it.

Note:
The line you marked in blue was a bit different from what it should have shown

load-module module-alsa-sink device=equalizer

With no Hash symbol at the begining...

1. Delete ~/.pulse/volume-restore.table and restart PulseAudio.
2. Are you sure that's a PulseAudio problem? You may need to change a kernel option for the ALSA driver, or else you chose the wrong output device.

If you enabled the equalizer, you must change the default sound device in a different way. You shouldn't edit /etc/pulse/default.pa (the line still say "device=equalized"); instead, edit ~/.asoundrc and amend the text I marked in blue in the guide, and determine the proper device in the same way I mentioned in my earlier post.

Oh, I need some advice. Loving Ubuntu so far but I can't get sounds from the system, applications, flash, nothing. I followed the steps from the tutorial, still no sound.

Here's my info, if you could point me in the right direction I'd be grateful, thanks............


The applications do not play audio and do list an entry in the Playback tab of the Pulse Audio Device Chooser

Part C, Step 3.

Thank you...this works flawlessly for me...(intrepid).
And i kinda like the equalised sound. But is there any way that i cud manually change the equaliser setting?? I mean like increasing Bass...or decreasing treble...??

Thank you.

Yes it's possible, but consider it a DIY job.

Read the text contained within ~/.asoundrc, and pay attention to the "controls".

Now, look at the output for the equalizer plugin that's used by this guide:

analyseplugin /usr/lib/ladspa/mbeq_1197.so

Note that changes don't take effect immediately; you'll need to restart PulseAudio.

Alternatively, disable the equalizer in PulseAudio (simply comment the line in /etc/pulse/default.pa), and using Audacious (with the extra plugins installed), enable the same LADSPA plugin, play some music and tweak the equalizer to your taste.

When you're finished, make a note of the LADSPA controls, input them into ~/.asoundrc, and re-enable the equalizer via /etc/pulse/default.pa.

so it was, all working now, thanks for your time ;D

i am also working with the same with this type of audio system. testing enable me to find out the faults and wrong connection.

Hello there!

ubuntu intrepid i386 laptop.
everything working fine exept a game called warzone. I have audio, but it is chopping(is it the correct word?) w-e-ll, so-und-s li-ke th-i-s. Refering the Part C appendix A troubleshooting part.
in the playback tab is warzone appearing and dissapearing every milisecound syncron with the m-u-sic o-r vo-i-ce what came out frome the game. The video is great. so i can play if i dont need the sound, but i need.
So i didnt see any suggestion for this kind of problem in your list so i wondering if you have any idea.

Have you tried finding the audio settings in the game options and changing them around? Most games that run natively will default to ALSA for some reason and you have to change them to PulseAudio yourself. If the game is running under WINE, make sure WINE is either set to use ALSA or OSS. In the later case, be sure to launch WINE with the "padsp" wrapper, to allow it to be caught by PulseAudio.

[imretokyo]

The game let me to change only the volume of the audio. and i dont use wine for it.

Thank you my lord
