With updated FairphoneOS 1.2.8:

  • HiFime DIY 9018D works perfectly, even with 250ohm headset (Beyerdynamics DT900 pro)

\o/

(still nothing with AudioQuest DragonFly 1.2)

Thanks @siltaar !
Could you possibly update the wiki with your findings ?

The changelog doesn"t mention anything about usb, so I didn’t re-check anything. Only, they switched left and right audio channels, so it could be a side effect when they updated some audio config file.

For the dragonfly, is it working with linux ? If yes, could you check the name of the Alsa driver it’s using ?

It’s working like a regular audio card on GNU/Linux, and AudioQuest announced a new version of the product for this year, as it’s known not to work with Android OTG, asking too much power.

24

OK, that is interesting thanks. Do you have a powered hub to check for power issue ? (i don’t)

Power is still the main problem, because when you plug a device in the USB port, it will at the same time :

  • draw from the battery
  • prevent you from plugging a power source
25

Anyone have problems with USB sticks? I have one with a micro USB connection that works when I plug it directly into my FP1, but the FP2 doesn’t see it at all. Not sure if it’s a general FP2 problem or because I’m using a self compiled FPOS.

26

As far as I have read, this might be a new bug introduced by the 1.2.8 update.

Plantronics Blackwire C510-M (USB headset):

Google play and some other apps will use it for sound output, but phone app doesn’t use it at all, which is disappointing!
The two “Sound Recorder” apps (oops! 1 version would have been enough!), don’t use the mic on it either.

None of the 4 buttons work properly. Each one just toggles between phone speaker on and phone speaker off :frowning:

Shame, it’s partially there!

Edit: jaymanu - in Skype the headphones work, but the mic still doesn’t (it just uses the internal phone mic as in the other tests). I don’t use whatsapp, so I can’t test that one.

thanks !
Did you also try with whatsapp or skype calls ?
