  1. Okay so I have the PX21's with the 7.1 surround sound adapter (DPX21) and so whenever I plug it in to my computer the Bass and Game sound controls seem to not work and the Chat control is the only one that works... anybody know how to fix this?

    I know this is an old thread, but this might be helpful for others having this problem (like I did)

    My dpx21's were doing the same thing, chat used to control sound, nothing else working.

    Here's how to fix this
    1. Go to control panel and open up sound.
    2. Select the playback tab.
    3. Instead of setting "Turtle beach PX21 Headset" as default, select "VIA High definition Audio" (or something like it, it may be different on your hardware)

    It will now route the sound through the digital optical cable rather than the USB.

    Enjoy working bass and volume control and 7.1 surround sound audio.

    Hello so I recently got the PX 21 and it is great but the only thing I cannot get to work is the microphone.
    I record my gameplay using HD PVR 2 Gaming Edition, when using the PX 21 I can hear all gameplay sound, but whenever I try to do commentary it does not work.

    Can someone please help me out here.

    I did exactly this (but yes my optical cable name was different) yet I'm still stuck with no DSS signal on my DPX21. Is there anything else to try to fix this??

    You are absolutely sure that you are selecting the right output? As far as I know, as long as the optical output is selected, it should give you the right sound, controlled by the "game" and "bass" nobs.

    Completely. And yes, it does fix the "everything is controlled by my chat volume" thing, but I've yet to see the Dolby Digital light turn on. I also have Virtual Surround checked in Enhancements and the light does turn on if I play the Dolby Digital "test", but it. None of the games I've tested will switch the light.

    Ahhh, yes I don't believe you can get the Dolby signal without the proper Dolby Digital Plus Software?

    I actually stopped using the DSS Processor on my PC, and just use it for my PS3, because there wasn't actually any benefit to using the DSS :(

    You're thinking of "Dolby Digital Live" (DDL). That's the process that encodes a PC game's mulitichannel PCM soundtrack into a single Dolby Digital bitstream. If your PC's sound card or audio interface doesn't have DDL, you will get Dolby Digital from DVD movies and the like, but you will not get Dolby Digital from PC games. Long story short, you need a sound card with DDL to get Dolby Digital 5.1 from PC games. There's an article about that on the Turtle Beach Support site. http://www.turtlebeach.com/support/entry/830516976/
    I hope that helps clarify matters.
