I will be extremely thankful if someone helps my with my problem. For last 2 or 3 days I haven't been able to get any sound in Chromium browser. It happened after I plugged my computer to a TV via hdmi cable. Now after switching back to my monitor and speakers I am able to receive sound in Firefox and all other applications seem to be working fine, just not the chromium. I tried both flash and html 5 and in both cases it's silence. Reinstalling the browser doesn't help neither.
But when the other user logs on (my wife) she is able to get the sound in the chromium browser in her user account.
