The sound player dont work properly in Linux Mint

I use firefox browser
thank you

@iglesiaz - Would you make sure your flash player is up to date? Audio issues are often related to an out of date flash player. Also, if you would open up the error console and let us know if it is showing any errors this would be helpful in trying to figure out what is causing this!

The sound player works okay on Firefox 30.0 with Linux Mint 17 on my desktop.

it work at last.
I updated the browser and everything is OK.
Thank you

@iglesiaz - All right, glad to hear it!
