There was sound on the idents, but I believe they were broadcast without the BBC logo at the bottom. It's not really considered the 'official' launch of the idents though, since it was just an overnight test.

Speaking of the 2's, I'm curious about them featuring in an overnight test transmission. I don't know if they featured the sound from the idents itself or just the tone but apparently they were shown prior to them launching 30 years ago today.
