Sound comes through right device, wrong one, or not at all

I'm having a problem with sound from websites not always working right, this problem did not exist under Win 7 when I had it working. I suppose before I go into more detail with the problem I should provide info on my OS, system, and browser.

Second display is a 32" flatscreen TV connected by HDMI cable.
Audio output is usually ether handled using the speakers of the TV, or using a Logitech USB wireless headset.

Browser
I have a choice of Firefox 32 bit, and 64 bit browsers, and for playing the game in question I have a Linux port of the game's downloadable client for windows.

I hope that's enough info.

Now for the problem.

I play a browser based game called RuneScape, (a Jagex game) and since I have been using Mint I have noticed that while the game is supposed to have 2 audio channels with their music on 1 channel, and 3 other sound groups sharing the other channel. Now, even though I usually have my sound set to play through ether the TV speakers, or the wireless headset, the game music is being played through the laptop speakers, and all other sounds for the game are not being played at all. The game is totally in Java with no Adobe Flash needed, so I have tested for the same sort of problems on other sites, and found that the sound works properly on other sites except for other Jagex game sites (which just don't play the sounds at all). Now normally I would be talking to the RS tech support people alone about this, but while Linux is not officially supported by Jagex, they do have a Linux tech support thread where nobody else has reported any sound problems like I'm having. Another reason I am posting about this here is that the sounds wo9rk correctly in Win 7, which makes me believe this is a problem with the interaction between Mint, and RS, not solely RS. I have already posted on the RS Linux tech support forum, and am waiting to see their reply to my latest post there.

Sites that use Adobe Flash like Pandora, and youtube are not having any problems.

If anyone has any questions that would clarify the matter, please ask, and I will try to answer clearly.
