FMOD sounds knob issues

[Dyno744]

While turning the MCP knobs, there is an audible issue in which the knobs only click after a couple of turns.

A clear and concise description of what the bug/issue is.

(I'm aware that OBS was unable to capture the screen correctly. The first set of clicks are from a close distance. But as the camera gets farther, you can hear the issue.)

Place an x to check the boxes:

• [x] Something found during a flight test
• [ ] FCOM reference included (issues are likely to be closed without this)
• [x] checked current FMC revision ident
• [x] Video included (where applicable)
• [ ] Screenshot included (where applicable)
