So I've tried a VGA to HDMI and i just saw that it wouldn't work. If i get a xbox 360 vga hd av cable will i get sound? I don't see the white and red ports on my monitor and i dont think there is speakers on it but will it still work? (with sound) I know i could get a converter also but will that also have sound?
If your monitor does not have sound, then no.. you will not get sound through the 360 VGA cable.
VGA does not carry a sound signal, the sound branches off either to a left/right (red and white) cable or a single jack depending on the particular cable you get. Some of them also have a port on them for optical out, which could be used to direct the sound to a surround sound system or similar.
I use a monitor with my setup without speakers. If you are using the HDMI (digital video and audio) output on your xbox, you still have the S/PIDF TOSLINK connector to carry sound. If your monitor does not have speakers, most likely it also does not have an HDMI connection, only a DVI connection. As long as your DVI connection can carry digital signal (very, very likely) you can use an adapter to change the HDMI to a DVI connection for your monitor, leaving only sound left.
You can use the extra sound connection to port your digital audio to a computer, a sound system, or anything else that supports it.
