last week i dragged and dropped some songs from itunes on my mac to sd card via card reader and then loaded them onto my treo 650 and all played well. today i loaded some more songs and lost the sound. the progress bar moves and countdown timer shows that song is playing but no sound comes out even at full volume. phone sound is ok even on speaker. i put card into my palm pilot t3 and tried songs and it sounds fine. wonder if i somehow wrongly fiddled with SOUNDS preferences.

ALSO, another question-the telephone has poor conversation clarity. my old cheap basic i736 had great talking/listening clarity. and had more bars in more places. anyone with any ideas?
