Is anyone else having audio quality problems with their HP 210 / HP 214? Maybe I'm expecting too much, but my hx4700 was excellent. I've tried a hard reset and I've produced the best quality MP3's I can - they play great via a hi fi system or on a laptop, but once on the HP 214 there's a high frequency hiss while a song plays - very noticeable on quiet classic stuff. It stops between songs so it doesn't seem to be a jack plug issue. If I route the iPAQ into the hi fi the hiss is still there - so that eliminates dodgy earphones. I'm using TCPMP and Pocket Player both have the same problem and I'm ripping with Exact Audio Copy and LAME 9.7 in secure mode. I'm on the verge of returning to the retailer as defective (reluctant as it's already chock full of business stuff) - but maybe there's a simple answer. Any ideas gratefully considered.
