I'm in the UK on android 1.5 still and I have slight (annoying) cracks/pops/audio interference - on headphones, speaker and using a AUX input in the car. This happens on podcasts (I use beyondpod to download and listen) - it also happens using music apps. I have tried putting it in airplane mode to rule out wifi/gps/mobile interference - no difference - also get same on and off charge. Topic: Audio problem 2.1 I was hoping 2.1 (when we get it in the UK) might sort this - obviously not reading the thread above! Next step is to transfer a podcast off the sd card and play on the ipod or pc and check for interference (in case it's somehow picked it up on download - doubtful). Also going to capture some audio and record it to see if I can record the audio with the interference in case I need to a log a call with TMobile. Anyone else have this issue - you would probably only notice on quieter music and spoken word tracks/podcasts. Someone on the thread above suggested to me about memory but I have no memory issues and adept at killing apps using advanced task killer.
