All is set but Play doesn't work

[Ste77]

RPi3 on Rune 0.4 beta with USB DAC and wifi connection.
Apparently all is set: network is ok, card recognized, USB HDD is mounted and tracks are on queue, but if I start Play button, track doesn't progress, counter remains on 0:00:00.
Same with Internet radios.
What is wrong then?

Have you installed Addons? If so, there appears to be some issues with them at present that the Addon developer is ironing out.

I had exactly the same problem.

I tried to "repair" it, but in vain.
I reflashed and set it up from scratch, no Addons this time !
