[PROBLEM] No sound: Pi zero w with Hifiberry DAC+ zero

[Tim Curtis]

To troubleshoot, first establish that a default config using the On-board audio device works.

- Turn off Bluetooth, other renderers, MPD replay gain etc.
- Set I2S device to "None"
.
.

- Reboot

Then verify that a radio station plays and that there are nor errors displayed or printed in the moode log. Note that you don't actually have to actually connect the On-board Pi RCA output jack to your audio system for this test.
