Hi,
I've looked through the various threads on this and don't see anything that quite corresponds to my issue, so I thought I'd start a new thread. I'm using a DAC+ Standard (H.W. 2.6 is printed on the board) on a Raspberry Pi 3 and can't get any sound through the DAC.
I've tried with Raspbian, PiCorePlayer and HiFiBerry OS.
I've also tried different SD cards and a different Pi. It doesn't work with any of those.
Using HiFiBerry OS 20200527 I have the following bits of diagnostic information:

Feeding from Logitech Media Server and playing in Squeezelite, music claims to be playing in the display, but nothing comes from the amp.
Do I need to provide more diagnostic information? I've never seriously used the DAC since buying it, but think it was selectable under Raspbian Stretch. However I never got round to playing sound through it until now.
Is it dead? Or am I doing something wrong? Or not doing something I should?
Many thanks,
John
