ASIO4ALL Official Home

Universal Windows ASIO Driver

Version 2.9 (beta 2)

Changes since version 2.9 beta 1:

Make WaveRT event mode strictly opt-in. It is broken in too many instances and may have caused funny and not-so-funny things to happen with onboard HD audio devices. There is a new checkbox now where you have to explicitely allow event mode (a.k.a. Pull-Mode) to be used at all.
Workaround added for extremely low bandwidth devices, such as audio devices on Toshiba Bluetooth stack (and possibly others), if you’re into that kind of thing…
Fix some minor issues WRT WaveRT resource allocation.
Add Workarounds for broken host implementations that violate Microsoft COM requirements. This does not completely fix anything, but rather helps to avoid crashes, while still losing functionality. BUT REGARDLESS IT IS _YOUR_ CODE THAT REMAINS AT FAULT, SO PLEASE FIX IT!

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…
