Ubuntu 7.10 Sound Stutters

Just done an update to Ubuntu 7.10 from 7.04 and now the sound and music streams is very Stuttery any ideas?

This is with and without the desktop FX and clean cache.


Thanks

Just tried to remove all the files and re-extract it and run it. Still the same, I don't know what to try now.

Was the upgrade to 7.10 a clean install? Things can get messy if you keep your old distro and decide to upgrade to a newer version installing it on top of the old one. I myself use Xubuntu 7.10 gutsy gibbon without sound stuttering, tho i have to admit i use a selfcompiled (2.6.23) kernel with integrated ALSA driver for my onboard intel8x0 soundcard. Newer 7.10 kernels seem to have (had) some soundproblems (like kernel 2.6.22-14, which was the last i used. the sound was fine for me, but setting the frequency at boot failed).
If you want, i could send you the "conf" file i used for my Kernelversion.

I'm not quite sure that's really the cause of your problem, but it was a pretty good guess. Don't you agree? ^^;;

Yeah the update was just via the normal update manager. Do you think your conf would fix this?

Also do you think a format and clean install would fix this?

Thanks I have only used linux since Feb so kinda new.

Does this help?

The "conf" file is just there to tell the kernel compile process which modules and settings it should use. so in case you don't plant to compile your own kernel, it would be of little use to you ^^;

And yes, a clean installation might help. It's at least worth a try, I'd say.
Apart from that, you could try out the different sound export settings at the "secondlife" script. Enabling "export" for a certain soundaemon means, disabling the sounddeamon for SL. They all work for me, but i had the best results with "esd". But only after i replaced "libesd-alsa0" with "libesd0". "libesd-alsa0" would stall after a couple of hours and produce annoying looping sounds. "libesd0" on the other hand works perfectly for me.
Happy trial and erroring ^_~

1. Do you think your conf file would help?

and

2. Do you think a format and fresh install would also help?

I am new to Linux but I am a fast learner

Thanks

Fresh install, same issue.

Did you try the "libesd-alsa0, libesd0" thing yet?

I had the issue too, I just switched to using ESD instead of ALSA, OSS and it worked beautifully, since ESD passes it to ALSA anyway it doesn't hog the soundcard either if you got mixing setup.

How do I make these changes? if its removing the # from the main file then i have tried all 3 also oss and esd

It's a bit more than that. You have to open Synaptic and then mark "libesd0" for installation. Synaptic will then tell you that "libesd0" and "libesd-alsa0" cant be installed at the same time. That's just fine. Just let Synaptic do its thing when you apply the marked changes (uninstalling "libesd-alsa0" ans replacing it with "libesd0" and youre done. Hopefully using esd for SL will result in a non-crackling sound then ^_^

I'm also having the choppy sound problem under Gutsy.

I installed "libesd0", replacing "libesd-alsa0", then uncommented the lines in "secondlife" to turn off OSS and ALSA, leaving the ESD line commented out.

No sound in SL at all =0.o=

At "etc/esound/" you should find a file named "esd.conf". It's content looks like this for me:

[esd]
# autospawning is not recommended, since it can't really be done
# right. If you want your login session to be using a sound daemon,
# you should start it from the session controller, not some random
# app inside.
auto_spawn=1
spawn_options=-terminate -nobeeps -as 2
spawn_wait_ms=100
# default options are used in spawned and non-spawned mode
default_options=

Setting "auto_spawn" to "1" makes esd start whenever an app requests it. I hope that will fix the esd problem for you ^_^

Sadly, my esd.conf was already exacly like yours.

I am glad that its not just me. I tried the new RC thats just out today, but still the same.

I am now hesitant to try what you said since Jillian has lost all sound, any other ideas?

Not all sound, just in SL. It's easy enough to reverse, go ahead and try it just in case my problem is specific to my sound stuff (which is one of those HDTek "Hi-Def" chipsets.)

It seems to be more than just us

Sad to say, same problema here.
I had this temporarilly right after install Ubuntu 7.04, but it went away after instaling a couple of packages, ESD I think, changing the sound system to ESD/Alsa then back to automatic...
No luck so far in Gutsy.
I've tried every suggestion in this post and the one recomended in it:
/263/80/212344/1.html

Did you try compiling your own kernel yet? it's really not that hard. And if you keep your old kernel and dont delete its grub entries, theres no risk in case the kernel you compiled wont boot. You can always return to the old one.
All you need is the kernelsource, which you can get here:

http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.23.1.tar.bz2

And from there you simply need to follow these pretty simple instructions:

http://www.falkotimme.com/howtos/debian_kernel2.6_compile/

Except at the end you musn't use "mkinitrd" but "mkinitramfs"

After your new kernel is installed, don't reboot yet, but change your /etc/X11/xorg.conf so that everywhere it said "nvidia", "glx" or anything else that is 3d driver related is changed to "vesa". Install envy (a 3d driver helper) which you can get here:

http://www.albertomilone.com/nvidia_scripts1.html

then reboot. once your OS is loaded with the new kernel, you can start envy so you'll get your 3d driver back. Hopefully envy supports gutsy gibbon now. Before that needed a little hack which you can find at the envy homepage tho.
Good luck ^_^

P.S.:
Oh right... It's most likely safe to use your old kernel config file, which the menuconfig command will load automatically. My guess is, that the Ubuntu guys patched the original kernel source and something went wrong soundwise because of that for some Ubuntu users.

I tried using PulseAudio instead of ESD, and SL's sound worked perfectly (turned off OSS and ALSA, forcing ESD (and thus PulseAudio)). Problem is that PulseAudio rather sucks compared to ESD for everything else.

**** EDIT: PulseAudio is NOT a solution. It's very problematic. Use ESD:

/263/9e/217645/1.html#post1725811

That' s it... sudo apt-get esound. If you have the ESD plugin for PulseAudio, let apt remove it!
Tested 32/64bits.
Set the Sound Configur in Ubuntu for Automatic and use ESD software mixing.
In the secondlife script force ESD by uncomenting the OSS and ALSA BAD variable.
100% now!

When I issue that apt-get command, I get:
"E: Invalid operation esound"

it sould be "sudo apt-get install esound", right? (well I guess, as that worked)

And, he's right! It works! On both my laptop and my desktop.

Royer da winnah! =^_^=

==== Edit: ====
Ok, not perfect. Only works if I run "secondlife" in a terminal window, otherwise no sound at all. This is likely the result of my playing with PulseAudio.

Hmm - I had the same problem after upgrading to Gutsy, did the "sudo apt-get install esound" magic and uncommented the two lines in the secondlife startup script - and everything works perfectly - no need for any terminal window.

Strange. But very glad to have it fixed, thanx a lot!

Ok I tried sudo apt-get install esound

Uncommented the ESD line, started SL and its just the same. I removed esound, commented the link and started it..it worked perfect...then closed it and opened SL again and back to the same issue.

Any thing else i should try?
