Sound setting reset after each reboot

[Feidreva]

Hi!

I have a Logitech USB headset on a imac Yosemite, and each time I reboot, the sound setting reset i.e. : I have to set each time in the system preference the USB OUT, In, And SOUND EFFECTS.
Is there anyway to have it set for good and not set it after each reboot?

Thanks for help.

I think I have the same issue: I almost never reboot my iMac but when I do, the sound preferences are reseted to default and I have to select USB again.
