Choppy Sound

Laptop running Unbuntu Gusty,

Realtek High Def Audio

When I get in SL all the sound is very choppy. Works fine in windows.

Thanks.

I would guess that something else is grabbing the sound so that more that one process if fighting for control. BTW do you know if the viewer is using OSS/ALSA or ESD? and do you what do you have KDE/Gnome (or what ever WM) configured to use. If its OSS then you will get choppy sound unless you ensure viewer is the only one using the sound system (disable artsd etc).

If ALSA or ESD is not an option its sometimes possible (a kde example) to use a wrapper artsdsp this redirects the /dev/dsp that the viewer is trying to open to the artsd sound server (on kde).

You can force the viewer to attempt to only use specific sound systems by enabling the LL_BAD_XXX in secondlife.sh

I was having pretty much the same problem under Mandriva 2008 x86_64 running KDE (also with a Realtek HD Audio). I've got sound as clear as a bell now, and it was a really simple fix, that I'll share for anyone else using KDE and experiencing choppy sound.

First, make sure your sound server is using ALSA. In the Control Center, select the Sound Server and either pick 'Auto Detect' or 'ALSA(OSS)'. The next thing you need to do is wrap Second Life with artsdsp, as Michelle2 Zenovka suggested. This wrapper only works on binaries, so you can't do:



Since that's actually a shell script. Just open the secondlife script in your favorite text editor (vim, right? ), and look for a line that has LL_WRAPPER. There should be a couple of examples there, mostly talking about running 'valgrind' or 'gdb' with second life. You can shove the artsdsp wrapper here, by adding a line like so right about there:



Then you should be able to simply run ./secondlife and it will be auto-wrapped with artsd, which has stopped all choppy sound on my system.

Hope this helps someone else out there!

I got choppy sound too...and why can't it just work well (without doing some difficult settings)???

In Ubuntu try apt-get install esound.
That should install the ESD sound system and remove any PulseAudio-ESD plugins.
Then startup Secondlife again.

Thnx Royer!

"apt-get install esound" did the trick, simple easy...what would someone need more??

Royer's solution worked for me too! I'm using Ubuntu 7.10 on a Sony Vaio VGN-SZ230P laptop. My audio worked fine in everything except SL, and SL's audio was fine when I booted into Windows instead of Linux. Now I have no problem. All the choppy/clicky/poppy noises are gone.

Thanks Royer, I have been trying to figure out how to fix this.

Ubuntu 8.04 comes out with PulseAudio working correctly and the install of ESOUND is not needed anymore!

Ah, I will be looking forward to that. Till then I can have fun with find solutions for the many bugs and errors I comely come across.
