I have iTunes on my PC.. pretty sure I'm running XP. I installed software that came with my new turntable yesterday evening so I could record some old vinyl. The software automatically records, converts to MP3 then sends to iTunes. (I usually convert the MP3 into an AAC file afterwards).. Everything was working fine even this morning. I recorded another record. It converted the tunes and sent them into iTunes. Some of the songs that were imported into iTunes were labeled "temp" which was weird but whatever and when I clicked on them to see what songs they were, no sound. I clicked on any other song in iTunes and they also would not play. I saw the status bar(?) moving and counting down as if it were playing and all, I just don't have sound. So in short no song either recorded and imported from the records or songs purchased from iTunes will play and also I inserted a CD to play thru iTunes and that would not play either.  Also, I played another record as if I was about to record it and sound is fine thru my speakers running thru my computer. So the issue appears to be in iTunes.. I have no idea what to do at this point.  Thanks for any advice in advance! Rob
