Ubuntu 7.10 Sound Stutters

Not shure if I understand you correctly, but the sound part of the 'secondlife' script should look like this:

## - Avoids using the ESD audio driver.
# export LL_BAD_ESD=x
## - Avoids using the OSS audio driver.
export LL_BAD_OSS=x
## - Avoids using the ALSA audio driver.
export LL_BAD_ALSA=x

Don't uncomment the ESD line! You WANT to force SL to use ESD.
And that's the original ESD, not any PulseAudio, Jack or ALSA emulation. That's why sudo apt-get install esound.

Changing the file to look like below results in zero sound

## - Avoids using the ESD audio driver.
# export LL_BAD_ESD=x
## - Avoids using the OSS audio driver.
export LL_BAD_OSS=x
## - Avoids using the ALSA audio driver.
export LL_BAD_ALSA=x

I think my breif flirtation with PulseAudio has something to do with that, which is to say - I probably broke something.

Upgraded to Gutsy today. Had sound stutter and tried all the ideas. Royer is right. sudo apt-get install esound worked. Thank you all for your help. Learned alot. Off to a concert!

Installed pulseaudio and pulseaudio-esound-compat forced SL to use ESD and all sounds a lot better.

There is a little delay every now and then but its definitely a lot better than it was. The music stream is perfect, the delay is on the UI sounds and the TP sound....it might happen 1 to 2 seconds later.

installing these extra packages and editing the conf file should not be needed, especially since it was fine in Ubuntu 7.04.

Has this been added to the SL bugs list? If not how can I add it?

Just noticed that Amarok now crashes on pause after installing Pulseaudio removing it doest fix the crash.

***** Ok a Complete removal of pulseaudio and a restart fixed this amarok issue....though now SL sound back to being broken

This isnt a SL Viewer issue. PulseAudio-esd emulation seems to come installed with the new Ubuntu and is broken. I had the sound craclking in Amarok and other players also.
Just try removing pulseaudio... and install the package "esound", should help all sound work in Ubuntu.

Yeah I know, I was just pointing out that this is one side effect of the fix provided. I tried the esound thing but it just resulted in zero sound.

found the same thing . update to gutsy had to disable 3rd party repositories. that might or might not be the reason esound doesnt work out of the box. dont know, but it did the trick. tousheee! now for some good blues!

Very weird....tried the esound thing again....opened SL still the same....started SL this morn and its fine...maybe the restart helped WOOOHOOOOOOOOOO

OSS is being removed from the linux kernel as of 2.6.23 in favor of ALSA. Alsa shouldn't require a sound server such as ESD, pulse, esound or such. Depending on driver support for the sound card in your system. Ubuntu 7.10 came out with 2.6.22 for it's kernel which seems to sometimes have some sound issues, reverting back to OSS should work but SL might keep other applications from using the sound card, including the Alsa sound system.

I've been trying the esd/esound solution here and I end up with no sound and this error:

2007-10-27T10:19:22Z WARNING: loadWAV: Could not load data '/home/alina/.secondlife/cache/f0f42e31-e219-eef0-53e5-65f9528631b4.dsf': This command failed because FSOUND_Init was not called

When disabling OSS and ALSA in the terminal I get this message:

2007-10-27T12:29:54Z WARNING: ESD audio output FAILED to initialize: Error initializing output device.

Dunno...I'm new at Linux

Okay, I managed to get the client sounds working (with slight delays in all interface sounds, I'm not sure why) but now I can't use anything else with sound -- I tried to use AmaroK or Totem and it didn't work.

Sound is still a bit delayed, but I installed esound and all that fun stuff, and made the entire computer use ESD and woot it works.

Except sound capture, I'll attack that next.

EDIT: Sound delays on entire system, ohmygod.

It would help if people would say what they are using as a desktop (KDE, Gnome, XFCE... other). I know KDE uses arts as it's sound server, and I have a work around which works fine for me with arts, am not so sure about Gnome and others.

With mine, I use Gnome. Ubuntu 7.10 Gutsy.

Okay, after some testing, i've found this (about Ubuntu 7.10 Gutsy running Gnome)...

OSS sound system works -- but it has the skippy sounds
ESD sound system (with esound) works -- but it has a 1 second delay on all sounds (even on other programs )
ALSA sound system (preferred of course) does not work.

I'm pretty new to linux, but i found it out simply by watching the terminal as Second Life ran.

Any sound server, ESD, pulse, etc will have delayed sound when playing a game that uses a lot of CPU resources. Especially if the system is a single core, there may not be any problem on a dual core or higher system.

Alsa will be built into the kernel soon as the default option as opposed to OSS.

SL uses SDL or what as a sound interface to the system? There seems to be quite a few issues on this, perhaps with the addition of voice this will be changed.

****Edit

Tested out 1.18.4(1) and the ALSA sound problem seems to be fixed. It runs and stays running with no need for a sound server. So no delay on sounds, unless it is the first time the sound is played and it has to be down loaded from SL itself. Also, looks like the font rendering is nicer.

Durrr?

Often dies after that, internal client sound death.

The Kubuntu thread at /263/83/228592/1.html covering the same problem, which may be of interest.

I run Kubuntu

Had the stutter problem, did the ESD install & supress OSS & ALSD. Now, if I launch in a window, no sound. If I launch full-screen, sound is good. If I use Edit Preferences to change to window, sound remains good. I don't expect other applications to be able to use sound while SL is running though.
