everyone. I am using Ubuntu 12.04 and chromium. The problem I am facing is that there is no sound notifications of the incoming message. After doing some search on internet, I found that may be this is because the flash player does not work properly.

However, I can see videos on youtube and some other video sites. I can even see the ads present on the websites. I have found a threads (How do I get adobe flash working in Chrome or Chromium on Ringtail?) in the answer of which describe the exact situation I am facing. That is: on one hand, the official website tells that you have no flash player installed; on the other hand, it can tell your installed flash player version.

I don't know how to fix this because the answer provided ask to delete .tmp file in home directory, which I didn't find exist.

By the way, the notification sound functions well on firefox.

You might be able to right click on the flash object, select global settings, and then on the right hand side, it'll say "Peer-Assisted Networking Panel" and enable each site. I have to do this in ubuntu 12.04 with webcam toys for chromium, so I figured it'll help you with another website flash related issue.
