Asio xp et wasapi W7, j'ai bien l'impression que c'est la même du moins chez Cakewalk ua25ex.
il est galement bon de rappeler le pourquoi d'asio. On est tres loin des besoins et attentes audiophile
ASIO (Audio Stream Input/Output), developed by Steinberg, is a cross-platform, multi-channel audio transfer protocol that is being adopted by many of the manufacturers of audio/MIDI sequencing applications. It allows software to have access to the multi-channel capabilities of a wide range of powerful sound cards.
ASIO expands on the basic capabilities of a standard computer sound card, most of which can only provide stereo (two-channel) audio input and output. The ASIO specification defines the interface that manufacturers of professional audio sound cards must use to create an ASIO driver for their hardware. This driver allows the host audio/MIDI application to "see" all of the inputs and outputs available on the sound card. The user can then assign these I/O ports as needed for recording or playback when using an ASIO-compatible software program. This allows the users to record more tracks simultaneously than the previous limitation of two channels imposed by a standard sound card.
Asio4all qui ne marche pas sans WDM

A: Good news is that you seem to have figured out that ASIO4ALL in general works just fine under Win98SE/WinME. Bad news is that you have no WDM driver for your audio hardware. The OS you use allows for two different driver models: WDM and VxD. To use ASIO4ALL, you need a WDM driver. Since about every other inquiry I get appears to be about this subject and in 9.9998 out of ten cases in conjunction with a SB Live! card of some flavor, this needs a SB Live!-specific answer in as far as you may want to check out the kx project drivers specifically designed for use with the SB Live! series of sound cards. If the prospect of a 48kHz locked sample rate bothers you: you can always run ASIO4ALL on top of kx.
A: After some initial troubles with earlier revisions, the driver now appears to work just fine with numerous USB devices. one thing to not do, I mean: not ever! is to check the DMA box with USB devices. If you do not need all the additional software gizmos like EAX, EQ, Fake3D-Whatever... it is recommended that you _not_ install the drivers shipped with your USB audio interface. Windows has a built-in generic USB audio driver that works with most devices. Thus, if you want to have honest, no-nonsense, low-latency audio playback/recording with your USB audio interface - by all means: stick with the Windows driver! This is especially true for consumer grade stuff, where you can be assured that the drivers shipped with it are most likely 'consumer grade' as well.
et dire que des gens entendent des différences entre DS/WDM et Asio4all.
