I’ve got a set of headphones with built-in microphone (aka “headset”) that is wired for use with (older) iPhones and iPads. It has a different wiring than headsets wired for use with Android phones.
It does not work with my FW13’s built-in audio jack–the headphone output works, but the microphone input does not.
This might be a LINUX issue, but I am wondering if it’s a hardware issue instead.
Questions:
Is it absolutely certain that the FW13’s built-in audio jack supports TRRS
I’ve used a lot of wired, TRRS headsets with both Android and iOS devices, and never had one work with one but not the other. Are you sure the TRRS plug is wired differently than standard? Edit: I know the in-line controls are not always the same and can sometimes cause issues with one or the other.
I have Fedora 43 and whenever I plug something into the headphone jack, it asks if it’s just headphones, or if it’s a headset (with mic). If you aren’t getting that question when you plug in, then there may be another way in the settings to enable the mic input on the jack.
I know this from personal experience (all my headsets are iOS-compatible–I tried plugging them into a game console wired for Android; finally found out online about the two standards).
If it helps, here is a page that shows the difference.
In most cases, plugging either headset into a normal TRS stereo headphone out jack always results in normal headphone function without any microphone input function, which is why I am asking if the built-in audio jack is only TRS output-only.
I don’t remember how the iOS headset behaved when I plugged it into the game console.
My guess from looking at photos of the FW audio jack board is that it is TRRS and not TRS, which should mean that it is wired for the Android standard, but it’s just a guess.
Yes.
The both the Framework 13 built-in audio jack, and the separate audio expansion card that FW sells use TRRS.
It’s not just android. It’s the standard that both PCs and most android devices use.
Apple always has liked to make their own incompatible things to force users to pay more for accessories. Sounds like Samsung has started following that line of thinking too.
The TRRS pinout has two different standards.
CTIA: Left-right-gnd-mic
And
OMTP: Left-right-mic-gnd
I don’t know the FW pinout, or what apple use or what android uses.
In general, the problem becomes:
user not pushed connector in far enough.
need to add an OMTP to CTIA converter adapter that swaps mic and gnd pins/rings.
I use USB headsets. They generally work better and have a single usb standard for what each pin does on the connector so less of a problem.
Although, there are still two methods to get audio from them. Usb digital audio or audio-alt-mode.
All the headsets i have use the usb digital audio method.
