The sample rate is a different beast to the buffer size. 512 is the largest the buffer size can go on that software.

44.1kHz is your sample rate = your computer taking 44,100 measurements of the audio wave every second....basically. This is the rate/quality at which analog is changed into digital.

It sounds to me that you've recorded in a certain sample rate, for some reason the playback engine has changed to a different one.

Have you changed any settings in the audio interface lately? Check your audio settings in your operating system also.

Sorry I couldn't be of much more help.
