PLOYTEC USB AUDIO JUNCTION 2.0 USB2.0 soundcard 192kHz 4in / 4out reference design. The Ploytec PL2 micro synthesizer is one of those 'just have to have it' devices that probably stands out more because of its diminutive size and affordability, versus how practical is actually is as an instrument/sound module. Ploytec made two versions of the PL2 - the black one is capable of live play using a 5-pin DIN MIDI 'In' connection.

'Universal Serial Bus' (USB) is an external peripheral interface standard for data transmission. USB 1.1 and USB 2.0 'full speed' operate at 12Mbps and provides up to 8 uncompressed audio channels at 48kHz / 16bit.
USB2.0 'high speed' (480Mbps), USB3.0 'superspeed' (5Gbps), USB3.1 'superspeed+' (10Gbps) and USB3.2 (20Gbps) offer higher samplerates, bitrates, lower latency and more audio channels.
You generally want a sound card with signal-to-noise ratio over 100dB, but the best sound cards are in the 124dB range, which is a significant improvement. Channels - A lot of decent, budget-friendly sound cards typically support 5.1 channel audio, but you can spend a little more to get one that can handle 7.1 surround sound. Ploytec GmbH does USB Audio drivers (Windows and Mac) and hardware for digital audio via USB1.1, USB2.0 and USB3.0. They do reference designs and a couple of audio and MIDI related products.
So called synchronous designs derive the samplerates from the USB clock. This increases the compatibility. e.g. it works with any smartphone etc. On the downside the audio samplerate contains more jitter, as there's on-purpose jitter on the USB clock from 'clock spreading' technologies.
Asynchronous designs use samplerates from crystals, external masterclocks or audio PLLs. If not in implicit mode, an additional USB feedback endpoint reports the rounded current samplerate, relative to the USB frame clock.
Implicit feedback means the driver uses the number of sample frames in the input stream's packets to construct the packets for output streams. No feedback endpoint is required and perfect syncronisation is ensured. This had always been the concept of Ploytec drivers.

Select the arrow next to Sound, video and game controllers to expand it. Right-click the listing for your sound card or audio device, select Uninstall device, select the Delete the driver software for this device check box, and then select Uninstall. Restart your PC. Note: Be sure to save documents and any other current work before you restart.
Windows WDM 'Windows Driver Model' audio is a basic standard, even supported by Windows Mediaplayer.
Mac OS X and iOS provide an advanced Audio and MIDI system called Core Audio, being part of the operating system. Many USB audio interfaces are 'class compliant', work out of the box on the Mac and don't need additional drivers.
Still, for interfaces needing a driver, Ploytec supplies a USB Audio HAL-plugin driver for Mac OS X.
