So it is one of four most likely situations, (1) Your microphone in your earphones are broken. This unfortunately can be quite difficult to fix unless your earphones have modular cables. But you might be able to fix it by cutting out the mic connection from where the mic is and connect it to ground. (2) Your earphones have a 4 pole jack despite not having a microphone. This would probably be fixed by making one of the poles insulated, which is most likely the pole 2nd nearest to the cable (3) Your headphones uses CTIA while your phone uses OMTP or vice versa. Adapters are sold which can fix that. (4) Your phone does not support earphones without a mic and using only 3 poles properly. Nothing can really be done on the hardware side then unfortunately as that is a software issue.

Did you use the same HDMI cable to test out your devices on the other TVs/try using another HDMI cable? If not, it is possible that the only issue is your HDMI cable. However, given that your other ports seem to have errors it is possible that it is an issue on the TVs board which would most likely require Surface mount soldering to fix. If you find a replacement board it will likely cost around $50 or so which would definitely fix the problem.

Have you tried turning it off and turning it back on ? If you have , back your phone up to a pc then reset it. Hopefully that helps since there are some rare strange bugs in android fixed by factory reseting your phone.
