Okay, I just made an account here, but i'll tell you guys this:
1) The Dazzles that are Silver and Black do not, I REPEAT, DO NOT, work online or with anything other than STUDIO! This is because the drivers are pretty much anti-everything minus Studio.
2)The Red and White dazzles do work with nearly everything. If the red 1 works with sound I don't know, but the they both work with Video I know that. This is because several of my friends on xbox used the red one and I have a white and silver 1, and only the white 1 works online, but I am having the same sound problem. I've tried everything, sound works in studio, but not in anything else.
If you have any questions, my gamertag on live is = MaX aKa PanTh3r
if you want to see my quality go to youtube and type in "xOUTI3REAKx"(I = i) and then hit my freebird million point video and watch in high quality as it is the only vid on there recorded with my dazzle.
Hope this helps anyone in the future
