The maximum sample rate that can be played with correct speed is XTALI/128. With 11 MHz
XTALI sample rates over 85937 Hz are played at 85937 Hz.

When full speed (FS) or high speed (HS) USB is used it is recommended that XTAL of
3
12.0MHz 0r 12.288MHz is used. The 32kHz crystal is optional, but required for RTC time
counter.
