Long Story short: The original FP4 USB-C to Audio Adapter doesn’t work. Neither with normal headphones nor speakers. Is there a (USB?) setting i have to change?
Details:
After i unsuccessfully tried out a few USB-C to Audio Adpaters, i checked again and saw, that they need a DAC to work with the FP4.
So i specifically ordered one (actually two) with DAC, that did not work. I thought maybe just ascam on cheap parts.
Yesterday my Original FP4-Adapters(!) finally arrived. They don’t work either. Tried speakers with external power supply as well as simple Sony in ear headphones, neitehr works. 3.5 mm Jack and USB-C are sitting super tight.
Bluetooth speakers work fine.
I bought the original fairphone USB-C-jack 3.5mm and it was working directly with all headphones I tried (small ones “in-ear” and “gamer headset with mic”).
Hi Pophicless,
Sounds like a problem with the USB-C port, but it could come from somewhere else, so don’t order one yet.
If you have a local #fairphoneangel they might be able to help testing a replacement module, or do you know anyone else who owns a FP4?
In any case, you should get in touch with Support before making any other move, and take their advice. You should insist on the fact that no adapter, including FP’s own adapters, has worked, with any earphone or speaker, and that you have already expended considerably trying to resolve the problem.
I don’t have any play/stop button, and the vol +/- are working (sound is increased/decreased) but without changing anything on the phone (I guess it’s acting directly on the helmet speakers, not changing the phone volume…)
Yesterday I tried to plug my FP4 in my car (Toyota Yaris 2009 with a jack input and NO bluetooth) and it DIDN’T worked
My config: FP4 (stock OS) → Fairphone USB-C to jack adapter → jack-jack cable → My car jack input
When playing my podcast the sound goes out of the phone.
Strange thing is that the USB-C is in “charging only” mode (even if not charging), and no possibility to change that:
The USB connection is controlled by the connected device (Appareil connecté), and if I click to “This device” (Cet appareil) after a dozen of seconds it says “Failed”
Weird it works for me no dramas, both fairphone brand and a couple of others, without changing any setting on stock fairphone os. But may be worth digging in usb /security settings
1st: even the “DAC” 3rd party adapter didn’t work, so probably no DAC at all
2nd: While trying out other adapters and following hints in the forum i ENABLED “Disable USB audio routing” in the developer options (i guess). After DISABLING it again, at least the original adapters work-with speakers and headphones.
But thanks for all hints from the community
cheerio!
Good work.
That quite often happens in IT unfortunately. The routing must have been disabled, despite the value shown in the UI and you enabled it by switching twice.
To enable Developer options:
Go to the app Settings
Go to About phone (last entry in the app Settings)
Tap 7 times on the last entry ‘Build number’
Now you get Developer options.
To go to Developer options, go to the app Settings,
go to System
go to Advanced
and there the second last option is: Developer options
scroll down to MEDIA
there you find USB audio routing
Did you manage to fix the issue? I bought the official Fairphone adapter, and had the exact same issue with my car (also a 2009 Toyota, I wonder if that’s related)
I also tried enabling/disabling USB audio routing but that didn’t fix the issue.
I’m thinking of trying another adapter but I don’t feel like buying adapters at random until I find one that works with my car.
I have a very similar problem as cjeam. Interestingly, my problem also started early November with a Fairphone adapter that otherwise worked very well for many months (and that I took incredibly good care of), so I am still suspicious this could be an issue due to one of the latest system updates (after all, I had another problem of “ghost typing” that also appeared after a software update - and thankfully was solved a couple of months later with another).
In my case I only have an USB audio adapter from Fairphone (so it doesn’t charge). When I ever so slighly move the phone the phone tells me I am now charging the device and stops whatever video/music I am watching/listening: if I click play then the sound comes out of the phone speakers. I tried not moving with the phone but it honestly makes no sense: I can’t listen to music walking in the street and have to stay completely immobile to enjoy music/videos. Sometimes I have to unplug-re-plug several times the adapter until the system stops thinking it’s a charger.
I will now try and buy another adapter as recommended by yvmuell, but I also want to share my frustration with this issue, one of many since I bought my fairphone less than a year ago. I have spent several hours trying to get to the bottom of this issue and should I want an adapter on yvmuell list I would have to go to a shop that is far from my home (as I don’t buy from amazon which I think is relatable to many fairphone users). I’ll buy one from another brand and will keep you posted if it works and solves the problem
For what it’s worth, thank you both for posting and yvmuell for the list. I’m annoyed at all the reading and self-repairing I have to do with this phone but I am at least glad that most of my issues were somewhat solvable and for the help I got from this forum. Hope it’s the same with this one as well
