Universal asio driver For wdm audio Instruction Manual

8. Always Resample 44.1<->48 kHz

ASIO4ALL can do real time resampling of 44.1 kHz audio to/from 48 kHz. Resampling will 

automatically take place whenever ASIO4ALL is opened for 44.1 kHz and the WDM driver does not 

support this sample rate.

There may, however, be instances in which case an AC97 will support 44.1 kHz by resampling internally. 

More often than not, however, AC97 resampling quality is extremely poor and/or prone to stability 

issues. To work around this, you can enable this option. With at least one incarnation of the SoundMax 

WDM driver (smwdm.sys), this option absolutely must be enabled in order to make it work at 44.1 kHz 

at all.
