Flash crashes constantly, regardless of whether or not I use Firefox, Chrome, or Chromium.

It does not always crash, but I would estimate it crashes 4 out of 5 times when loading a page. It seems to be most likely to happen on pages that have more than one Flash item. It also happens when Flash has to make a transition of some sort. For example, when Youtube switches from an advertisement to the main video, then it might crash. Also, some sites are more likely to crash than others. Vimeo will crash with almost 100% reliability. Youtube is fairly stable, and crashes maybe one out of five times.

I have tried uninstalling and reinstalling Flash. I have tried the Flash-Aid plugin, but none of the options it presented helped (in fact, it always ended up simply removing Flash and not finding an installation candidate).

I think it might have something to do with how Flash is connecting to Pulse. Part of the reason I suspect sound is a problem is that I had to get help to get Flash to work with my sound before.

As far as I understand it, all that's different about my sound system is that I go over a network to connect to a Pulse sound server on a different machine, and that I've hardcoded the server IP and port by adding a line that says PULSE_SERVER= in the file /etc/environment on the client machine. That's basically it, I think, but for more specifics, there are details here.

Unfortunately, it seems that Flash doesn't like this set up. It's maddening to have Flash be so unstable, so I hope someone can advise on how I might diagnose and solve this problem.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

I am not saying that this is impossible to solve, but, like many proprietary programs (OS-independent), Flash gives you very few options for diagnosing or fixing this kind of problem. The best that you can do is send a bug report to Adobe and hope that they fix it. – InkBlend Mar 31 '13 at 17:25
@InkBlend: I actually doubt the problem is with Adobe. Flash works fine on three other computers of mine, and the one where the problem is, it has a particular sound set up. – Questioner Apr 1 '13 at 7:01
@DaveMG - probably wise to describe exactly the sound setup you have for this PC with the flash issues. Should hopefully give someone a clue as to the issue. Is this restricted to one user - or if you create another account, does it still occur? (i.e. system wide vs local) – fossfreedom Apr 1 '13 at 9:35
@fossfreedom: I'm certainly not opposed to describing my sound set up. The only hold back is that I'm not totally sure I understand it fully myself. A very helpful member of AskUbuntu more or less set it up for me, and, other than the fact that Flash is crashing like a North Korean rocket, I'm hesitant to tinker with it. I will endeavour to work out what pertinent details to provide. – Questioner Apr 1 '13 at 10:44
@DaveMG I am not suggesting you not to use flash, just trying to narrow down the bug ;-) Have you tried the Flash Player debugger ? – desgua Apr 2 '13 at 11:54

Which version do you use? Have you installed the correct version of ubuntu-restricted-extras. I had a problem more or less similar to this but got fixed when I reinstalled the correct version of U-R-E from the software center.
