Universal Windows ASIO Driver

Version 2.15 (Beta 2)

This version supports Windows 10 only. Older versions of the OS may (and likely will) still work, but we no longer claim to be supporting them.

Changes since version 2.15 (Beta 1):

Fix: Sometimes, sample data was truncated to 16 bits on high resolution devices.
Fix: “Internal Heap Overflow” – message with 32 bit applications on some systems. 64 bit programs were not affected.
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.
Further GUI cleanup

Advanced configuration

Once the control panel has been switched to advanced mode, things begin to look a little more complicated. The device list is now expandable and you can enable more than one item at a time. The device list contains Devices, Device Interfaces and so called “Pins”. Devices are independent hardware units most of the time.…

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 usually…

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…

Hardware Buffer on/off

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…

Kernel Buffers/Buffer Offset

If hardware buffering is disabled, this control lets you add up to two more buffers to be queued for audio output. Each additional buffer increases the output latency of the device by the time it takes to play one buffer. Therefore, the initial setting of “2” should only be changed on less powerful machines, where…
