I am on 11.10 64bit and I have installed flash from

I had downloaded install_flash_player_11_linux.x86_64.tar.gz and moved to ~/.mozilla and ~/.mozilla/plugins

I also have OSS installed because alsa does not work for me. I generally follow steps mentioned at and everything works fine.

But for 11.10, flash has no sound. I am not sure if that is OSS problem.

There is a adobe-flashplugin package on the partners repository, have you tried it instead of the manual download ? – João Pinto Oct 16 '11 at 7:53
Yeah. Sorry I forgot to mention that. Same problem with the above package – Amey Jah Oct 16 '11 at 8:01

I had a similar problem in Ubuntu Oneric Ocelot 11.10 32bit. I was able to hear sound from flash movies, but it would work in all other applications and even Pandora radio.

I was able to fix it by doing

$ mv ~/.pulse ~/.pulse.bak

then logging out and logging back in.

I think some settings file was botched by an upgrade to pulse, which the flash player depends on.

For more information, check out:


I've noticed that after updating my flash player today that I am no longer having this issue.

If you have performed the fix mentioned above and were having issues with your sound icon remaining a flat line and needing to control your volume using alsamixer, this update appeared to fix that issue for me as well.
