Q: Why can't I record or play at 24-bit resolution?

The short answer is that WDM audio drivers only support 24-bit audio if the

application is using Microsoft's new “extensible” wave format. Many existing

apps do not support this format. This only affects programs that use the

wave/MME or DirectSound APIs.

The long answer to this question appears up above, in the general WDM

discussion.

Q: Well, why can't you guys make 24-bit work? Your old drivers

worked fine.

Yep, they did. With the old drivers, we were a lot closer to the action- we got to

see the audio format that the application was requesting. With WDM, we don't;

there are now several layers of Windows code between us and the application.

(Again, for more information about this, see the general WDM discussion above.)

Please be aware this would affect *any* WDM driver; it's not our bug, it's part and

parcel of WDM audio. However, that being said, we are looking into a

workaround. Stay tuned.

Q: Really, why don’t you guys support WDM on Windows 98 or

98SE?

One of the problems we have with running a WDM driver is we are largely at the

mercy of the WDM audio subsystem in Windows. WDM audio in Windows 98 is

more or less broken. Windows 98SE is better, but still has a significant number of

problems. It’s not worthwhile for us to try and support something like that.

There is a patch for Windows 98SE which corrects many of the problems with

WDM audio; however, it is not directly available for download. If you want to
