This is strange. Has anyone experienced drop in speaker volume (not refering to the earpiece during phone calls)? I'm pretty sure the volume of my Treo was set at about 90% - the second highest notch. The screen tap and the ring tones were significantly softer than normal. Increasing the volume doesn't help either. And all this happened when the Treo was connected to the PC via USB sync cable. Eventually, I had to soft reset the Treo to fix the problem. Any idea what had happened? A bug?
