3.5mm JACK on new Jolla Phone

[MeeGo-Junky]

Did you try this to get the USB DAC run?

Problem with USB DAC playback

Finally I got my FIIO KA11 to stable route audio over the DAC (at least until reboot, including listening multiple folders of flac and mp3 files stored on the internal memory and switching to internet radio back and forth) . I did follow more or less the steps described here: Beware of typos in the text, e.g. section 3: ‘pactrl load-module module-udev-detect’ is incorrect ‘pactl load-module module-udev-detect’ without r is correct.

It worked on Xperia 10 iii and also Volla Quintus phone nicely
