Gary.

Believe me when i say i respect your presence on pg over the years.

I’m just trying to help via my own experiences over the years//problems running recording rigs.

The reason i asked bout 44.1/16 is from past posts here it seems some recording rigs have probs when 48khz is chosen as sampling rate.
I would try 44.1/16 across all apps and see if any difference.
I personally have no ‘stuttering’ probs.

As your prolly aware to keep it brief most music apps use the technique of ‘filling audio buffers’ before needed. Ie ‘look ahead’.
Your prolly aware , but i’ll mention anyway….for other folks reading these forums new to bb…IF (from my experiences also in programming)...there is a problem filling the look ahead buffers , then stutters can occur.
Its sorta like a car that ‘coughs’ if its not getting needed fuel.

You said ‘All other applications that I have used outside of Band in a Box, including Cakewalk, work correctly with no stuttering. If there was something wrong with the audio card or drivers, then why isn't it happening outside of BIAB in other applications.’

With greatest respect Ive found from many personal experiences with sound devices over the years one cant assume such.

Another question….
Do you get the ‘stuttering’ when ONLY bb is running and all other music apps are closed ?
in addition have you run a latency monitor app ?

i'm just suggesting ideas to think about.
as i said before it would help pg support prolly if you posted a pic of your bb settings...thus if ok..its something else off the possible problem source checklist.

Happiness//best.
