- Hardware accelerated direct sound capture driver support using the Windows CE2 HAL API
The Windows 95 VxD HAL API doesn't support DirectSound capture. MS added a capture HAL API to Windows CE2 which is available on MDSN. I borrowed this API for the OSS driver and added support in the Direct Sound code to use the standard winmm api or the new one. Unfortunately, the driver side of this isn't finished. I have a version using select for notifications but select is not well supported in OSS and the OSS buffer size restrictions complicate this even more. I am still trying to find a solution that is fast and works under all conditions but I'm afraid I will need to go back to a timer based solution (hopefully just as a fallback).
