Welcome to the forum. In the future, you can get more attention to BIAB problems by posting in the BIAB Product forum, whether Windows or Mac as appropriate. It's several below this forum in the list.

BIAB has a "speed up" option that allows playback to start even if the file is not finished regenerating (which is what happens when you first press Generate/Play). But before I can recommend a setting, can you please tell us about your system:

Is this a Windows PC or a Mac?

What is your system like? CPU & RAM specs in particular, if you know it. If you do not have a fairly recent powerful machine, then please download and run Geekbench, a free utility whose score can tell us whether your computer has enough power to run BIAB with the faster options.

Which version of BIAB do you have?
