We’ve been having an issue with audio playback since updating to 1.4b2 WEC2013. It seems that audio playback of .wav files in slower than it should be, and the pitch is slightly lowered. The scope images below show the duration and frequency measurement of what should be a 1kHz test tone played for 5 seconds. However, the tone is played for 5.48 seconds, and measured to be ~913 Hz.
Any explanation and/or fix is greatly appreciated.
