Because I have a lot of lossless FLAC music on my phone (I am old guy and like local stored music, I don’t use music streaming platforms ), and there is no easy way to add Bluetooth AptX HD and other high-quality codecs to Pulseaudio SFOS I decided to buy good wired headphones.
I tested my my old headphones and I am surprised because:
- 3-pin TRS headphones are recognized correctly by the OS/phone (everything works as expected),
- 4-pin TRRS headphones (with microphone) are not recognized by the OS/Phone (no sound in headphones).
The question is - is this SFOS limitation or the hardware limitation? I am asking, because another phones which I tested - on all this TRRS jack type works correctly (Xiaomi, Nokia, even iPad tablet, etc.) - and I hear the sound and I can use built-in microphone for the calls.
It is also strange, that sometimes phone suddenly stops discover normal headphones (3-pin TRS) and I need to reboot the phone to get this jack socket working again (but fortunately it is rare case). That I am wondering if it is SFOS problem and what is the OS process responsible for this…
Can somebody test this on Xperia 10 III and give me here feedback?
I want to buy Koss Porta Pro headphones - there is 3-pin version without microphone and 4-pin with microphone, and I need to know what to buy / where is the problem - with my phone or with OS…
