when i was running 8.10 when it was in beta i was missing a package for flash audio but i forget what that package was.
but that doesnt seem to be the issue

:lolflag: got it! upgraded to Flash 10, doesnt like Flash 9 for whatever reason.

I've got the same problem... It started today... I've got Flash 10, so I'm not sure if I should Downgrade to 9 or what....

Well, Any suggestions?

try uninstalling flash and then get the new one from here http://get.adobe.com/flashplayer/

I Uninstalled Flash, then I downloaded it from the link, reinstalled it, tried Youtube... Nothing, ubuntu then prompted me to update my flash to a newer version, so I did, still nothing...

Also, just so you don't ask, Yes, my volume is up....

OK, so for no good reason, it just started working again.

This is not the first time this kind of thing has happened, and each time it happens I really wonder if my friends who think Linux is full of pixies and gremlins fighting over my computer are right...

Just a thought, haven't had enough coffee yet... so my thoughts are not good yet..

Same problem here and it's getting downright discouraging. Sound sometimes in all apps, sometimes only system sounds, sometimes sound just quits but comes back with reboot. Was just watching a youtube video and sound just cut out half way through. Arrgghh!!!!

If I can't solve this once and for all, I will be forced to go back to windoze.

Yep... just use operating system running alpha-status...

use alsa mixer. Go to System>Preferences>Sounds and select your sound card(if you have 2) and make sure it has "Alsa" on it somewhere. Then uninstall pulseaudio with

sudo apt-get remove pulseaudio

That should work since I had the exact same problem!

I had this same problem... all though it is not the recommend way to run pulseaudio it fixed all my issues with no sound on startup. If you are on a single user linux box then imho there is only benefits from running it at the system-wide level

system-instance = yes


I also changed the following in daemon.conf - I believe this fixed my issues with scratchyness

resample-method = src-sinc-best-quality (i set it to the highest,,, change it to what you want it)
high-priority = yes
nice-level = -11
default-fragments = 5
default-fragment-size-msec = 25

Also I set the following to the best (also highest cpu)...
resample-method = src-sinc-best-quality

from best to worst the options are:
src-sinc-best-quality, src-sinc-medium-quality, src-sinc-fastest, speex-float-{10-0}, speex-fixed-{10-0}, ffmpeg, src-zero-order-hold, src-linear, trivial
