Hey guys, Just got my new Sound Blaster Z in the mail this morning. After some research I found that I should set Windows Sound settings to 5.1 Speakers non-full range in order to best utilize the SB drivers. I use a pair of Razer Carcharias (stereo headset). I don't have speakers. Supposedly, by doing this and turning on SBX Surround I'll get simulated surround in games and listen to stereo music just fine simply by turning off SBX Surround when doing so. Well, games sound great with simulated surround, FLACs stored on my computer sound great and crisp no matter what Windows is set to (Stereo or 5.1) BUT Youtube videos sound awful. In order to get Youtube videos to sound good I need to go into Windows CP and set the sound options to Stereo Speakers. Once I do it goes back to sounding great again. It should be noted that I only use Youtube for music. As unlikely as it may sound, YT is an amazing resource for classical music. You can find a lot of performances by different conductors / orchestras or soloists if a solo piece and you can create your own playlists. It's kind of a big deal to me. Everything else about the card is amazing. Windows 7 x64 Latest Firefox Latest Creative drivers (Jan 2014 as of this post) Problem: The sound loses clarity, it becomes muddy and the bass is way over the top. If I crank the volume too high, the sound becomes distorted. Not pleasant at all. This doesn't happen in the slightest with music stored on my hard drive, only YT.
