[Q] echo with aux cable - Lollipop 5.1 topic

Hi, I have noticed that if i use AUX cable (with 2 cuts - only stereo and without microphone ) during a call there is a HUGE echo effect for the caller.
I have verified this problem also with AUX input of my car and with earphones (without microphone). This bug is coming out after upgrade to lollipop 5.1. If I'm using earphone with microphone i do not have any problem.

So I can summarise the issue in this step:
- nexus 5 with lollipop 5.1;
- voice echo for the caller using aux cable or earphone without microphone;
- using earphone WITH microphone i do not have any problem.

Any of you have noticed the same problem, or you can check out?

Do you know if there is already some solution to this problem?

Thanks in advance

Ivan
