Game Crashes at "Press Start" Screen!

[lugia56]

Hello and this is my first post so sorry if I write nooby comments. I have a problem with Dolphin 3.5 on Mac. Originally when i got Dolphin, it worked decently but didn't run games very well. I then fidgeted with the settings until i got what i wanted. I then found out that in Mariokart: Double Dash!! the song wouldn't play after the second lap. So I then downloaded the stuff I needed to and got LLE to work. But the sound wasn't working correctly so I used regular HLE instead. After that I noticed that my games weren't working right. They would boot up and show the Nintendo logo. Then they would show all the other logos like they should. But right before it goes to the "Press Start" screen the game would crash. After that no matter which sound I use the game would keep cutting off the sound 1 second at a time and then working for 1 second in a pattern. I then deleted the files for sound i added and changed the settings back to default and it didn't do anything! Please help!
