Hi, 
 
I have a strange problem occurring with a trrs connector. I have a trrs male connector that is wired the same way as the HM901 (not AK240) on a balanced cable to IEMs. When I first wired it, it worked flawlessly in both TRRS and TRS. Then I switched connectors and switched back, now it still works perfectly in TRRS but when I put it into a TRS female the right side cuts out. If I leave the left side IEM earpiece off, then the right side plays fine. As soon as I connect the right side IEM, the left side pulses on and off and goes dead.The only thing I changed the second time was that I soldered the shielding to the sleeve to ground it, but I'm not sure how that could make this happen. Thanks. 
 
Can anyone help me with what is going on and what I need to do? Thanks!
 
Sincerely, 
 
Edward
