NO Sound with Flash 10 plugin in Firefox 3 after 8.10 upgrade was working in 8.04

I've tinkered with it some more. I've got the sound set to pulseaudio and it's playing the audio and video for flash 10 in firefox 3, ok now. I did an uninstall and reinstall yesterday. Rebooted a few times today that may have helped, but can't be for sure. VLC wouldn't play streaming radio stations from Shoutcast. It had worked fine in 8.04. I opened the radio station with Xine and it played fine. Closed Xine and then opened station with VLC and it worked fine after that. Sound seems flaky in ubuntu 8.10.

audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Failed to connect stream: Invalid argument

I'm getting this today when I test the pulseaudio in the sound settings. Sound won't play in some apps today. It was working ok last night. The problem seems intermittent. Is there anyway to go back to 8.04?

I am having the same problem, any ideas on how to solve it??

It worked a few times, then quit working when i rebooted. Flash 10 in firefox 3.0 is not working in my ubuntu 8.10. Flash 10 worked fine in my ubuntu 8.04 before i upgraded, which now seems to be a downgrade. pulseaudio won't make any sound when i hit the test button in the sound settings. Flash 10 firefox 3.0 works on my other PC that has ubuntu 8.04 loaded on it with it set as autodetect..

As far as I can see, this is a showstopper. No sound from Flash!

 I searched google and ubuntu and couldn't find a fix. I have wiped out my 8.10 install and reinstalled 8.04. I'm listening to AOL radio on the PC right now and can view youtube videos once again. The release notes make no mention of sound problems like this, but when you search ubuntu website you can find 255 of them and you can find a bunch of them on google search also. We can hope that 9.04 fixes the sound problems. Maybe this isn't the best distribution for older PCs like mine. I will test the Live CD the next time before upgrading next time. This is the first upgrade that i've had to roll back.

Why is this marked "solved"?

@ Bobby Reynolds

Please tell if this is solved and please tell something about your solution...

Hope this helps

Finally did a whole bunch of stuff and ended up with Flash working in Mozilla.
Some history:
Found a page at https://help.ubuntu.com/community/OpenSound , folloowed *all* the instructions (including, near the bottom those relating to Flash)
Stopped Mozilla, restarted and *Flash worked!!*
But.. Rebooted -- Flash no longer worked in Mozilla. Movie Player (Totem) went gray and I had to "force quit"

... So I went back to the same web page and found the link about "Reverting to ALSA"
followed that to http://ubuntuforums.org/showpost.php?p=5539687&postcount=331
and then to http://ubuntuforums.org/showthread.php?t=962695 to reinstall ALSA -- including a reboot, and at this stage it gets confusing because I can't recall which instructions I followed. SORRY!!

At any rate Flash in Mozilla and Totem both now work, System sounds are on and I am a happy camper.

Really sorry about the lack of a precise audit trail.

I will tell everyone how to fix this issue now.... lol. Alsa or OSS will not work properly with an aftermarket sound card, unless you go into your bios, and under the "integrated hardware" section you TURN OFF your integrated sound card. Linux upon loading tries to load the correct drivers for the PRIMARY sound device. This is your integrated card in most instances. It is the equivalent of having to delete/disable necessity within any version of windows. I promise you that if you follow these steps, YOU WILL HAVE SOUND!!!! I just did it myself, and I am a noob.... figured that one out on my own, after realizing that Linux based programs load the hardware in the beginning of booting the OS (or whatever you would like to deem the proper term for ubuntu). I am using a Creative Sound Blaster Audigy SE, on a dell Dimension 1100... yes 1100.... lol It's old but flying. Linux is slow? riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiigggggggggggggggggghhhhhhhhhhhhhhhhhhtttttttttttttttttttttt.... I am glad I finally took the step, the next is away from Bill Gates and his empire.....

I stix it to the man....

Hope this helps anyone that tries to figure it out.

Dude:
http://onlyubuntu.blogspot.com/2008/11/fix-for-no-sound-issue-in-ubuntu-810.html

That did the job for me, NOTHING else seemed to work so I was glad this did.

sudo killall pulseaudio
sudo alsa force-reload
    (Hit the reset confirmation)
and then go to System>Preferences>Sound and change everything to ALSA

Voila, thanks to that guy, woot!

I installed Ubuntu a week ago and have been searching for the answer to this ever since the day I installed it. I've tried more fixes that I can even recall and not a single thing did anything at all... until... djclay2009's post two up from this!! That was it! My sound has been great on the whole system EXCEPT when watching streaming video in Firefox. Disabled the integrated sound card as he said and restarted. (insert Hallelujah Chorus here) It worked!!! I have sound in streaming video again!! I don't understand why Ubuntu wanted to mess with the integrated card for streaming video only, but it's fixed!!! THANK YOU CLAY!!!!!

sSoulraKk provided the best solution for my case: Ubuntu 8.10 on Toshiba Tecra A4
After applying it I had only to restart Firefox (which hung and I had to kill it).

Thanks a lot !

Thanks to sSoulraKk this worked for me after days of painstaking struggle with various other solutions. Thanks .
