Seems to be solved.
The two GPIO lines I had connected through the DAC board to the
touchscreen seem to have disturbed the DAC.
Disconnected them and since then could not reproduce the issue.

Thanks, will do.
I also discovered that the two additional GPIO pins I had connected are
not needed.
So I will first disconnect those, then test. Afterwards, if it is still
there, I will power the display completely separately, and try again.

No good news.
Capacitor in between DAC and display power did not work at all (DAC gave
no output). Removed it, got audio again, but with the above described
issue.
Then I put several capacitors at the 5V power input of the Raspberry Pi.
No change.
How is separate powering of the display done?
:D:D:cool:
OK, got it. Yes, I have in fact seen this symbol. Never thought about it
very much. Now, I know more.
I will place a stabilizing 220µF capacitor within the power connection
between DAC and display and then look how it works. Because this is
quite easy to implement.
If that works,

Well, of course I could power the touchscreen separately. Just have to
figure out how to do it.
Another idea: Insert a large Electrolyte capacitor at the output of the
5V supply. How do you think about that?
What is this lightening bolt?
A power supply can be putting out proper voltage, but creating noise.
I suspect certain DACs are more prone to noisy power supplies. I have
all kinds of setups running for debugging.I have some that always
run with the lightening bolt.yet they never lock/ crash.
Do you have a way to
I initially had the "official" Raspberry Pi 2.5A supply.
Already suspected the power supply (especially now with touchscreen
attached) and bought a 3A supply (noname).
Unfortunately, the problem still occurred.
Should I nevertheless try the CanaKit one?

Hi guys,
I have an issue with pCP 3.20 (normal) on RasPi 3 Model B, an iQAudio
DAC+ and official 7'' touchscreen + JiveLite.
Sometimes (regularly, but not any time), the DAC crashes after having
switched off the player and on again. No audio output any more. LMS and
Squeezelite seem to be
