I/O Console is an external box with analog and digital I/O audio jacks and volume control knobs. It is always bundled with the remote control. The I/O Drive Box is an internal 5 drive with analog and digital I/O audio jacks and volume control knobs. Also bundled with the remote control. Cards with UAA support (CA0112, integrated in CA20K2 for Titanium cards) can perform basic functions with just the supplied Windows driver. All Creative cards have 3x 1/8 inch jacks for analog headphone/speaker output (2 of them are 4-segment-jacks for a total of 7.1 sound output), some partner's cards such as AUDIOTRAK Prodigy 7.1e and Auzentech BRAVURA and Forte have separated headphone output. All Creative cards except XtremeGamer have 1x shared 1/8 inch jack for either: Line In / Microphone / Digital Out / Digital I/O Module. The optional Digital I/O Module is an external box for handling digital IO: 1x Coax In, 1x Coax Out, 1x Optical In, 1x Optical Out. The XtremeGamer card has 1x shared 1/8 inch jack for either: Line In / Microphone / Optical Out (TOSLINK minijack). It does not support the Digital I/O Module. Some partner's cards such as Auzentech Prelude and Forte has separated 'Line In / Microphone' and 'Digital I/O' jack. For the PCIe X-Fi cards, remote control support requires a USB receiver and is sold separately. The Titanium HD lacks analog surround sound outputs. X-Fi Xtreme Audio The entry-level model of the X-Fi series, the Sound Blaster X-Fi Xtreme Audio, does not actually have the EMU20K1 chip but is a re-branded Audigy SE, using the same family of chips (CA0106-WBTLF), and even the same drivers. Thus, not only is all of the X-Fi–related processing performed in software, but it also lacks basic hardware acceleration just like the SB Live! 24-bit, the Audigy SE and other budget Soundblaster models. The X-Fi Xtreme Audio does not use the same drivers as the rest of the X-Fi family (and lacks ASIO), some games do not recognize it as being "X-Fi capable hardware", and the device's hardware profile resembles that of older Live! and Audigy cards. [This wrong. I had both cards,the Audigy SE and the X-Fi Extreme Audio - they are not the same. The Extreme Audio has a Cirrus Logic chip known from the Audigy 4, has more capasitors and sounds well, where the Audigy SE and SB24 are totally outdated in sound
