loud pops after last firmware and mcu update

[Wei Cao]

If you get a chance to test it, please let me know if it works fine with the elder firmware.

yesterday I have downgraded the mcu firmware to 2.5 and left Xmos firmware at 3.30.
after unplugging usb there was a loud pop when the dac went into stand-by modus.

Hi Koen, Thanks for your info.
We also tested with our Mac Mini, but we did not reproduce the issue you met.
 Looking forward to your further test results.
Thank you again.
