Somebody, please, post a guide for SGS2

I don't have sound on my SGS2. I installed Xiialive lite and I tried Dolphin HD, Opera and Firefox beta. Dolphin HD and Firefox were set to iPhone as the user agent. I also tried different bitrates. As soon as I hit the start button, it does seem to buffer and to start, but I don't hear anything at all.
What can I do.
Btw., I don't want to use the yourmuze.fm app.
