One of the most persistent problems in the ZC and ZQ betas is that SPC files play too quietly, resulting in the volume being turned up(and frantically down when programs are switched).
But those days might be over. For some reason, I think it might be the sound buffer size; doubling or tripling it might amplify the volume, taking care of the problem. But I digress; I could be wrong entirely, and waiting for a complete lecture on sound buffers, or I got lucky in some way.
Hey, I can take straight and honest answers. Don't be lenient on me. 😉
