Broad yes, it sounds like white noise. Very loud white noise switched on briefly every 100ms or so, as each packet is transmitted. So it sounds like a fast click-click-click-click. I actually ran into this problem with our headphone chip, where if the right kind of headphone cable were connected, the cable would receive the transmitted RF coming from our external antenna and send it back into the unit, where the headphone amp would act as a radio, demodulating the RF and outputting the _envelope_ of the signal as clearly audible clicks to the headphones. A couple 22pf caps on the output effectively shunted the high frequency RF to eliminate the problem, but it was not easy to track down. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=34406 _______________________________________________ audiophiles mailing list [EMAIL PROTECTED] http://lists.slimdevices.com/lists/listinfo/audiophiles
