On the DInc, the mic worked with headphones plugged in. On my TB, the mic doesn't work with headphones. Is this a new "feature" downgrade or just limited to my device?
I noticed a similar problem when plugged into the aux input on my car's stereo. When plugged into the stereo thru the headphone jack and a call comes in the person on the other end can't hear me unless I unplug the cable from the headphone jack. I am also unable to hear the caller on the car's speakers. This is very annoying and hopefully something that can be fixed in an update.
Thanks! I got it to work using that setting. Only thing is that it's a little annoying that the letters TTY are always showing on my status bar now even when I turned it off. Oh well at least it works now.
I was having a similar issue with the Bose SoundTrue Over ear using my OnePlus One. When I tried the TTY VCO, it successfully made the microphone on the headphones work however then I could not hear any sound from the call via the headphones. I wish I could figure this out...I like the headphones.
