Since upgrading to Jitsi 2.4.4997, I do not receive notification sounds all the time. For example, when a call comes in, the pop-up tells me the phone is ringing but it does not play the sound. If I am chatting and the other person sends something to me when I have the chat window covered by another window, it does not play the sound. It does play the sound if the chat window is on the top and has the focus. The sound works correctly when I click on the Play button in the Tools->Options->Event window and it worked correctly before the update.
Background, I am running Windows 7 Professional on a Dell laptop with Intel Core-I5 and 8GB of RAM.
Please reply with any questions that you may have.
Thanks in advance,
