Using external RAM doesn't sound good

[yoav-klein]

Hi Earle, I'm trying to use the AudioFileSourceSPIRAMBuffer class with the 23LC1024 chip, and for some reason the stream sounds somewhat broken, distorted. In the serial monitor, I get now and then this line:

STATUS(buffer) '99' = '###############################################################'

I'm using GPIO4 as CS, and also using a Adafruit I2S DAC if that helps.

Any idea why is that? Does it work fine for you?
