    Hi i tracked my rogue note problem down by resolding all the resistor but I still get this terrible sound when the cut off it turned up. Please see the last 20 seconds of this video to see what i mean, thanks!

    also it doesn’t happen when I use the headphone jack and my volume knob doesn’t go all the way down to silent?

    Nick,
    That’s the speaker being overdriven to the extent that it’s voice coil is hitting the speaker magnet. The little on-board speaker isn’t meant to reproduce the sound very accurately, it’s just meant as somewhat of a monitor to let you know the Macchiato is making sound at all. So it can be misleading when it causes problems like this. In fact, the next version of the Macchiato (which we are currently working on) will not have an on-baord speaker, partially to keep issues like this from happening.
    To cure this problem, just lower the volume of the Macchiato.
    Sorry about this issue.
    Take care,
    -Brach
