Topic: Fireface 400, Noise on powerup

Hi guys,  new to the forum but have been using my Fireface 400 happily for over ten years.
Yesterday when i plugged in my equipment i noticed an electronic whine through my monitors and headphones as i powered up
the fireface.
It only happens on initial powerup but is a little worrying.
I have linked a sample recorded on my phone

This only happens with the power supply.
If i power the unit via firewire, there is no noise.
Otherwise the unit is working fine as usual :-/

Any ideas?  Should i send my unit in for repair?
Thanks

Try a mixer reset and then flash this state into the unit (Flash current mixer state).

Thanks for the response.
Ok, i reset the mixer Options/Reset Mix/Total Reset
Then selected "Store Current state into device / Flash Mixer"

Still the same noise when i power up with the power supply.

Any further recommendations?
Thanks again for your help.
