Question

After buying StdudioLve 34 SX and downloading the latest software, the sound is crackling on all USB outputs. In 44.1 less intense, in 48khz very strong and occur irregularly. Playback sound on the Firestudio Project card has no glitches. Played on the monitor via HDMI connection also has no glitches. It is also not after ripping and playing on another device. I have recorded all sessions so far on the Firestudio Project at 48 khz.

Answer 2

I solved my problems by lightening the usb ports, checking in my motherboard was connected a firewire card that I no longer needed so it was eliminated and my mac is now fine and the presonus is back to work very well
