From the first day i bought my MI2 I have notticed a very strange sound coming out of the headphones output when connected on my car stereo. Firstly i tested with other devices on the same car stereo and there was no problem or stange sound at all. After a lot of test and thinking, i figured out that this strange sounds stop after you put something to play. Even if you raise the volume to the top and you here the beep sound immidiatly the strange sounds stop for a few seconds and then start again. I'm almost sure it is hardware related. After some more research i found out that some other devices using the snapdragon proccesors suffer from the same issue. I think the sound processor is embemded in tha cpu. Waiting to hear your thoughs and opinions. Thanks.
