I just updated Universal Control and ioStation 24c to the newest versions (ioStation 24c firmware version 3.5). Before I did this, everything was working flawlessly...afterwards though, ANY audio that plays out of my computer (Studio One, Youtube, Music Player, ANYTHING) there are pops in my speakers before the audio plays. Once it plays, it sounds fine, but theres like a 1 second delay before it plays where the speakers pop.

I have uninstalled Universal Control and ioStation firmware and reinstalled. I have made sure my Windows settings are the same as Universal Control (48khz, 24bit). It almost sounds like everytime I play audio, the interface is having to switch sample rates or something, even though I have made sure Windows and Universal Control show the same sample rate / bit depth.

This is almost unusable now - it was PERFECT before the firmware update. Does anyone know what to do???


EDIT: I opened a ticket and support told me to downgrade back to the previous firmware version. I did this by holding the "Prev" button on the ioStation while power cycling it, then when it restarted, I pressed the glowing red "Read" button - this factory reset the interface. Then I uninstalled Universal Control, and downloaded the previous version of Universal Control (you can find old versions on the Universal Control downloads page). Once this older version was installed, It gave me the option to update the firmware to version 3.44 (the version before the new broken 3.50). Everything works again!!! Avoid that new firmware like the plague!

EDIT 2: After rolling back to the previous firmware and version of UC, the really loud pops did go away, but now I am having smaller clicky pops. I have tried everything.
