HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

[vprasaj]

Stuttering problem is gone.

I did Part A and C on my 32 bit ubuntu hardy (mint elyssa beta). Flash was ok before.

For my 5.1 sound i edited /etc/pulse/daemon.conf and changed
; default-sample-channels = 2
to
default-sample-channels = 6

Now my sound system is complete!

Thank you psyke83!

Now i did what Part D says but after that there i couldn't get any sound from my pc except rhythmbox. I tried to watch flash video on youtube and listen mp3 on imeem.com in firefox3b5. Even i couldn't hear the sound when i logged on. The worse thing is that when i try to play a video in movie player my pc totaly got locked. I also try to run movie player with comand

$ padsp totem

Then i modified /etc/asound.conf like in Part A and changed the /etc/pulse/default.pa with the original one. Firefox and the other things except movie player got fixed.

Now i will uninstall "swh-plugins" package with command

$ sudo apt-get remove swh-plugins

then try run movie player properly.

Does any one have any idea what is wrong with this things? I am using toshiba A105-S4094.

[beytun]

I removed the package and now movie player works fine too. Is it possible that movie player and swh-plugins have some disconformity?

@psyke83
Thanks for the help about the plugins.

But first I have fix pulseaudio itself..
I guess pulseaudio doesn't what it should. I have managed that in now starts it self. In stead of give a segmentation fault. PulseAudio Manager works also. But different programs didn't play sound.

At this moment part A and B I have done. Part D was installed, but I have removed it again, but that seems not the problem.

Rhythmbox didn't give sound.

De output of verbose is displayed below. When pulseaudio is start. I start Rhythmbox and try to play a number, but that fail and give the last lines of the output below. When some dutch message are a problem, say it, then I will translate them.

Do you have an advise what to do?

@psyke83
Thanks for the help about the plugins.

But first I have fix pulseaudio itself..

I'm afraid I don't see any problems from that output, and I'm not sure what your problem is.

I would recommend you undo all the changes from this guide (Appendix 2), then check if your PulseAudio is running normally.

Then, apply Part A, log out and in, and see if things work. Then follow the other steps as long as things still work ok.

[psyke83]

I removed the package and now movie player works fine too. Is it possible that movie player and swh-plugins have some disconformity?

No, that shouldn't happen. Try to undo all the changes from this guide and see if things work ok, perhaps.

[pingpongboss]

The equalizer part of your guide was awesome! Thanks

[Sordelka]

Woha thank you so much. It works without any problems!

[OmahaZ]

Thanks indeed psyke83 c|;o)

Improved soundquality throughout - no stuttering and no tincan sound anymore.

No difficulties whatsoever with your guide.

Would it be possible for you to add a comment at the bottom near the downloadable files (flash and default.pa.txt) that one has to be a member of Ubuntuforums to get the attachments?

[steveneddy]

Part C, #4 (Optional) fixed my stuttering audio.

Thank you.

This is the only fix I did because I already had the new kernel and it still stuttered.

Not sure, but I think I just squashed my last bug on my laptop since installing Hardy.
