Is there any further information on the state of the problem? The firmware update doesn’t look like it’s fixed the problem, only minimised it. This is an issue for our SQ6. Attached an mp3 of the sounds we are getting when recording via USB-B to a MacBook Pro.
I’m getting a similar problem with our SQ6. Recording via USB-B into a MacBook Pro (running macOS Sierra). Using the USB port on the right side of the MacBook (next to the HDMI port). Other ports in use are both mini display ports using dongles (one to HDMI and the other to ethernet)
here’s a clip of the type of sounds I get. Again intermittently.
