This isn't an issue with your rom in particular. Out of all the roms I try I always try Youtube first because I get one of 3 things happening:

1. Youtube works flawless
2. Youtube works, seems to buffer fine, audio seems fine, but video is like a picture slideshow
3. Youtube sits at connecting or buffering, have to try a video many times before it will work. When it does work you either get no audio or you get the problem like #2.

I have a Sprint TP with an 8gb SD in at all times. Though I get the same problem whether the SD card is in the phone or not.
