Fixing Flash Sound issues in Firefox

You don't hear anything when playing a Flash video or it just doesn't sound after pausing and playing?

Install

sudo aptitude install alsa-oss


sudo vim /etc/firefox/firefoxrc

You will see a entry like

FIREFOX_DSP=”none”

Change it to

FIREFOX_DSP=”aoss”

Please note that these issues are usually noticed with the older versions of Flash.

Maybe you should upgrade to the latest version of Flash for Linux.
