    Default Sega CD won't play music cds

    Hello, I have a Model 2 Sega CD and it won't play music cds, by "play" i mean by not playing the music even though they system will detect the amount of tracks and the length of each song. I have also tried outputing sound out of the Left/Right Jacks into my stereo but with no luck. I have tried using model 1 genesis systems (multiple systems with stereo mixing cable) and my model 2 genesis, still no music. I would like to add that this system does read games and plays music and sound effects from the games. I would also like to note that I bought this system broken (blown fuse) and I bypassed the fuse to make a working system, I have no idea if bypassing the fuse would affect the system by not reading music cds. Can you help me?

    I don't think the Sega CD can read some newer made Music CDs. Probably because they are written faster than what the Sega CD can read at. I tried playing my Legend of Zelda: Ocarina of Time OST and it doesn't play. Yet it works in every other CD player in my house, including my Sega Saturn(s).

    If anything, it's some form of copy protection locking it out. Some newer CDs basically require an approved device in order to read, just the RIAA sticking their dicks a little bit deeper up our asses, thanks to our pussy cunt government that sides with the people that already have more money than god and didn't do shit to deserve it.

    It can also be that the bits are less pronounced and therefore can't be read properly. Is there any data on that LOZ OST CD? that could trip it up as well as audio CDs with bonus data wasn't around back in the days of the Sega CD.

    There is no such thing as a CD being a "certain speed," when you burn a CD at 1X, 2X, 4X, 8X, etc. etc. you are just literally burning the same bits at that speed multiple, but the actual bits burned are identically spaced, etc. The only reason people recommend burning at low speeds is because of the concept (sometimes false) that the bits will be burned better if they are burned at a lower speed because the laser will spend more time burning each bit. A CD burned at 1X and 8X will be exactly the same, except (ideally) the 8X bits will be slightly lighter and may have problems with a relatively weak CD player.

    The only time a CD was burned at a different rate was the Dreamcast GD-ROM, which is how they increased the data to 700MB to 1.2 GB by spacing the bits closer together and running the drive at half speed. This is why CD-R DC games must be carefully optimized in order to not wear out the DC laser from too much back and forth reading from a standard disc that would normally leave the laser stationary (I find voice samples the worst offender, like in Propeller Arena and Fatal Fury: Mark of the Wolves)

    None that I know of. I'm positive my Ocarina of Time OST is a regular old music CD.

    Well I don't think my OOT OST is new enough to have a form of copyright protection, since I was able to rip the music off it without needing special software to get around protection. So what else could be the answer? I still think "being newer" has something to do with it. Maybe not the speed it was burnt at but maybe the quality of the disc or spacing of the bits like you said.

    I have tried many Audio CDs, some being from the late 80's and 90's. Sadly, theres still no sound.
