If you want to have shorter waits, use lower fragment sizes.

yes , setting of lower fragment size is my requirement at the moment in OSS application . i tried to use SNDCTL_DSP_SETFRAGMENT ioctl to set lower fragment size .

In theory, this should work.

but audio driver uses default fragment size only and not the fragment size desired by application .

Does it return an error? If yes, try moving this call before some other parameter setting ioctls.
