Windows ASIO Driver


2/16/2022: Version 2.15 released!

This version officially supports Windows 10 and Windows 11.

It has been confirmed to also work on Windows 7 and Windows 8, with only minor visual GUI artefacts.


Changes since previous 2.13 and 2.14 release:

  • Fixes and workarounds for on-board audio on newer AMD systems (like Ryzen 5000).
  • Fixes and workarounds for Intel® Smart Sound Technology (Intel® SST).
  • Workaround for Oculus VAD
  • Fix crash with Blackmagic Design DeckLink drivers.
  • Fix GUI visual distortion on high DPI display.
  • Add WaveRt packet support.
  • Fix: Sometimes, sample data was truncated to 16 bits on high resolution devices.
  • Fix: Sometimes, a cryptic string was appearing as USB device channel name inside host ASIO settings.
  • Changed AsioGetChannelInfo() to group channels by individual device.
  • GUI now showing the audio data format currently used, instead of the capabilities, for any active item.
  • Fix: Some audio devices were not detected.
  • Add full Unicode support for visuals.
  • Instruction manual now online, accessible through a GUI help button.
  • Completely dropped support for “ReWuschel” and Off-line settings. You could still re-enable “ReWuschel” by setting a registry key, but who really still uses software that is more than 20 years old?
  • Avoid using “Stereo Mix” loopback input in default configuration.
  • Device aggregation

    Device aggregation

    Using the button next to each entry, you can now selectively enable/disable each particular item in the device list. This way, you can also create multi-device-setups (“aggregate devices”) . Multi-device-setups require that all the devices involved are running from the same clock source. You can achieve this by daisy-chaining devices via S/PDIF etc. On-board devices… more

  • Latency Compensation

    Latency Compensation

    Since ASIO4ALL does not have sufficient knowledge of the underlying hardware/driver architecture, it can only guess the actual latencies involved. With these sliders you can compensate for the latencies unknown to ASIO4ALL such that recordings in your sequencer software are properly aligned with the rest. Note: In multi-device-setups the largest respective value of all devices… more

  • Hardware buffer

    Hardware buffer

    Note: For WaveRT drivers, this box is labeled “Allow Pull Mode (WaveRT)” instead! Enables the hardware buffer for the highlighted device. This only works for so called “WavePCI” miniports, as other types of WDM drivers do not usually allow direct access to the hardware buffer. Adjustment for best hardware buffer performance involves the “ASIO Buffer… more
