Audio Delay increment changes from 50ms to 500ms

Hi,

with the latest release (3.6.8) the increment values of audio delay settings were changed from 50ms steps to a whopping 500ms.

Was this intentional? I cannot think of any logical reason why this was done. It is practically impossible now to fix any form of delay with these values (except mulitples of 500ms), it renders the feature more or less useless. :(
