USB-C to 3.5mm jack adapters known to work with Sailfish OS

2026-07-15 Update: Jolla announced an official USB-C headset for August.

TL;DR This is not a thread for if but a thread for what.

While the were already a few discussion about that, the main subject was mostly if there should be a jack on the phone or what was the best solution to have deported audio.

Let’s face it, new phones don’t have an audio jack (with Jolla Phone 2026 as the first Sailfish OS-native device) and some people want to use a jack for some reason(s) that we are not to discuss (at least here).

The purpose of this topic is to make a list of adapters and that have been tested and works to help people who need/want one buy the option that suits them best.

There was at least one report that some adapters do not work for phone calls, it would be interesting if someone could confirm (or better yet, infirm) that.

If someone can convert this post into a wiki, it would be welcome as I didn’t find a way to do it.

I think useful information would be:

  • Tested for audio output/recording/phonecalls(/Android apps?) and if it works in each case.
  • Reference for the device (manufacturer website if possible).
  • Which phone was used (and maybe version of SFOS).

Adapters

Headphones

In some cases, the only requirement is wired headphones so USB-C headphones would be acceptable as well.

Other solutions

To avoid

Maybe it would be useful to list some references known not to work but it might require cross check (another adapter works on the same phone) to ensure the issue is indeed with this specific adapter.

Note: the people mentions are mostly to get confirmation of the reference for the tested device and maybe the phone with which it was used and can be removed if preferred.

The cheapest chinese ISY adapter works (ISY IKA-1000)

Would be also good to include what workaround ppl used for non-working ones (someone mentioned symlinking some files, but never details sadly)
Edit: idk I tried to suggest it twice and sadly got no specific response, maybe teaching ppl proper forum etiquette is in order so we can avoid ‘yay fixed it’ responses in the future

True.

I’ve added the ISY one, can you tell what was tested?

  • Which phone/SFOS version (“for quite some time” is fine if there were several updates of SFOS during use)?
  • Which use cases were tested (phone calls seems to be an issue)?

This thread is pointless. Any usb dac will work on sfos. As long as it works on linux it will work in sfos. There’s no need for thread “confirmed to be working with sfos” because anything that works on linux will work on sfos, it’s literally just alsa

Even if you’re right, you said “as long as it works on Linux” and not everyone is using Linux on a daily basis (until they have their first Sailfish OS phone, that is).

Also, this is meant to help people buy something, they may want to be sure it works before buying.

Just tested phonecalls mic also works, so from my testing everything seems to work (except media control, double tap for next, triple tap for prev do not work, but that’s a different subsystem and it also didn’t work on Xperia XV)

I’ve got the “KiwiEars AD1” USB-C DAC dongle to work reliably on the Jolla Phone 2 for sound output (sounds good for in-ear-monitors, but it does have a fragile cable), after creating a symbolic link to a config file, executing those commands in the terminal:

cd /etc/pulse/xpolicy.conf.d/
devel-su ln -s usbaudio.conf.disabled usbaudio.conf

I could not test controls or microphone as my headphones have neither.

Thanks so much for the details, ppl with same dongle/buds will now be able to self-medicate (and who knows might be a generic fix for all DAC dongles)

:backhand_index_pointing_up: This. Exactly this.
USB audio just works unless they did something really stupid; which would account for <1% of devices.

I would agree with you except we already have an example of a usbc audio dongle that doesn’t work and has special needs, who cares what % it is if there already is a working workaround, great to have it documented and you can now revert to complaining about a useless thread
Edit: and frankly it’s the same with the charger thread, theoreticians claim ‘DOESN’T MATTER, IT’S ALL COVERED BY THE STANDARD’, yet there were chargers that would break nintendo switch, but in theory they shouldn’t have, yet nintendo screwed up in implementing usb standard, I’m sure threads: this charger works with switch; were also swarmed by theoreticians claiming just charge with whatever, and here we arerdit: no matter what the theory says practice still eludes it and is what is actually on the ground, so thank god for practical threads

Then it has special needs, not SFOS.
If you want to document the special needs stuff; go nuts - but miles and miles of “this works” is really useless. Heck, even counter-productive as people might think everything else does not.

To the best of out knowledge Jolla did not mess up - and until there is reason to believe they did; no list required.

This equally useless thread isn’t exactly brimming with activity.

And that’s why this thread is here, so ppl can share their practical experiences, shutting down the thread because it’s useless, everything should work in theory, is useless as already demonstrated by practice, apparently they did eff up as one dongle type doesn’t work ootb
Edit: or claim it’s the dongle’s fault, no diff to the buyer, listing dongles that effed up is still useful for potential buyers, being a: theory says NO, helps noone
Edit2: also not sure what you mean with bt thread, last update march 2026

Omg I had forgotten. Let me quickly try it on my JP2026.
[..] It seems to get detected (I see the volume change), but sound still comes from the speaker.

Haven’t you read? It’s supposed to just work!

The thread is worse then useless - it is harmful. People will think they have to buy only what is tested and have a really limited selection if they buy in to this nonsense. The average user will lose more trying to follow the lust than just getting something normal.

Ah, yes - re-solve ll the world’s problems everywhere in triplicate. The universe thanks you.

And two posts in 2025 - none in 2024.
Last post 2025 - 2023 before that.
Positively overflowing with activity.

Very likely not the fault of the dongle.
Does any normal dongles work on JP2026?
Perhaps hold off on listing a gazillion dongles before that has been sorted?

And yet we have two dongles that break your theory of everything working, geee who would expect practice to not be 1=1 with theory. If 90% of additions here turn out to be ‘working’ then the thread can be renamed to ‘non-working usbc dongles’, so far too early to tell, listing dongles that don’t work should be fine with you I hope?

Well, yes and no. In response to your advice, I purchased an apple dongle and the ’ Stouchi USB Type C to 3.5 mm’ dongle. Both from evil amazon. The distinction was that one, the Stouchi thingy was immediately functional at full volume and the other, apple dongle, required intervention to get the gain to something like reasonable.

Soooo, @attah, do you all maintain there is not point in this discussion? Somthings work out of the box, one way, some, an other.

And I’m certain some junk doesn;'t work at all.

My point is that those cases are better off with a thread like this:

…instead of endless lists. You will have a generic problem, or five. Not a gazillion individual ones.

There will always be new junk. No way any list can keep up.

That’s purely because apple’s dong defaults to 40% volume, but it doesn’t change the fact that it is functional

Same thing happens on desktop
