The final revision of the original Sound Blaster, the Sound Blaster 2.0 was released in October 1991,<ref>{{cite web|url=http://ibm-pc.org/manuals/other/creative/SoundBlaster2.PDF |title=Sound Blaster |website=Ibm-pc.org |access-date=2016-07-17}}</ref> CT1350, added support for "[[Intel 8237#Modes|auto-init]]" [[Direct memory access|DMA]], which assisted in producing a continuous loop of [[Double-buffering|double-buffered]] sound output. Similar to version 1.0 and 1.5, it used a 1-channel 8-bit DAC. However, the maximum sampling rate was increased to 44&nbsp;kHz for playback, and 15&nbsp;kHz for record. The DSP's MIDI UART was upgraded to [[full-duplex]] and offered [[time stamp]]ing features, but was not yet compatible with the [[MPU-401]] interface used by professional MIDI equipment. The Sound Blaster 2.0's [[Printed circuit board|PCB]]-layout used more highly integrated components, both shrinking the board's size and reducing manufacturing cost.

Owners of previous revision Sound Blaster boards could upgrade their board by purchasing the V2.00 DSP chip from Creative Labs, and swapping the older DSP V1.0x with the newer replacement. The upgraded board gained the auto-init DMA and new MIDI capabilities of the Sound Blaster 2.0 but not the expanded sampling rates. The upgrade was necessary for full compatibility with the [[Windows 3.0]] Multimedia Extensions upgrade.
