Bug Description

Binary package hint: flashplugin-nonfree

Audio in certain flash applications is delayed by about a second. For example try this:
http://www.najle.com/idaft/idaft/
On Windows: no delay between interaction and audio playback.
On Ubuntu: one second delay untill sound is played --> no fun.

Googling for "Ubuntu flash audio delay" brings up a ton of forum threads with similar issues, but no solutions whatsoever, so I am making this a bug.

I tried fiddeling with the pulseaudio settings manually to maybe decrease audio buffer size or something, but the thing is too complicated and I couldn't figure it out.

Used firefox and latest flash from the repos with Ubuntu 10.10 current.

I can confirm with Ubuntu 11.10 and Flash player 11 downloaded from Adobe's website. I don't know whether it is a problem with Adobe's plugin or whether the problem is on the Ubuntu side.

The problem can be observed very easily in this Flash game:

Just wait until the character jumps through the glass (which happens after a couple of seconds of playing) and notice how the sound of the breaking glass is delayed by about 1 second. Makes that specific flash game unplayable.

I just wanted to mention here a workaround found on a forum (sadly I do not remember which one) :

Create the file /usr/ocal/bin/firefox (sudo vi /usr/local/bin/firefox) and write in it :
#!/bin/bash
PULSE_LATENCY_MSEC=20 /usr/bin/firefox "$@"

Give execution rights to everyone on this file (sudo chmod a+x /usr/local/bin/firefox).
