Some sounds have disappeared.

[wb5dx]

I have had my Inspire about two weeks and have thoroughly enjoyed trying out the myriad of available apps. However, in my experimentation, I have somehow turned off the "screen selection", "screen lock", and phone dialing (touchtone) sounds. I did check to see if those items are "checked" in the sound utility - they are.

All of the other sounds appear to be functioning.

So, what did I do? They are not critical, but I would like to restore them and know what happened, just in case something else occurs.

Thanks.
