Radio on but no sound.

[Myoung73]

Got into my 03 s today and the stereo (stock CDR-23) made no sound. The head unit turned on fine but no sound coming from speakers except a very faint high pitch noise regardless of input tried turning off and on, turning car off and on, fiddling with settings etc. Nothing worked. Thought it might have been the amp maybe. Got home from my ride and removed the fuse in row d number 9 which is marked audio system or something like that. It's a different fuse than the radio. Anyway looked at the fuse it looked fine. Put it back in and the radio now works fine. The fuse didn't look dislodged or anything when I first looked at the box. Wonder if the system just needed to be reset or something but that doesn't sound right. Anyway works now but figured I'd share in case anyone else has a similar issue.
