Flash Player Not working with youtube with Maxthon webrowser

Hi,

I cannot get the adobe flash player to work with the built in youtube with the maxthon browser if anyone is familiar with it. It been about a week now. Maxthon is a cloud based browser and they have a rendering mode called retro mode and when I click on that it just brings me to you tubes page and when I click on a video it gives me a black screen  and Up to it gives me a red rectangular box  and it says you need a adobe flash to watch this video download it from adobe but when I do that it just brings me to a troubleshooting page. It's not working in ie11 either I get the same message. I like the retro mode because It allows me to run all of the videos out of all 4 of my speakers. and I have everything set to quadraphonic sound  with my onboard realtek sound. I can play everything on my computer out of all 4 of my speakers just can't do it with you tube With the maxthon web browser in retro mode,. Its the only browser I think that would allow me to run the you tube videos out of all 4 of my speakers. If I switch to Ultra Mode or html5 they work but I still would Not hear them out of all 4 of my desktop speakers. I have active x filtering turned off in Ie 11 I have shockwave flash player enabled in the add onsa section of Ie I re registered some oc files. I have you tube added to compatability mode in ie I have the latest versions of flash installed flash 22 npapi and flash 22 ppapi and I have the adobe. So I'm not sure if flash has been disontinued for retro mode or what.

Could anyone please help me.

thank you.
