Hi
I have tried everything under the sun to get a PI3 (/proc/cpuinfo below) working with a HifiBerry DACplus. The hardware all previously worked fine with an old install of OSMC, however I upgraded for a couple of reasons to latest OSMC(Wifi network not working right, version very old and I forgot password in the end).
It seems whatever I do I cannot get the HiFiBerry to be recognised now. aplay -l will only list what I think is a HDMI output. I've also used lsmod and all relevant modules seem to be loaded. I cannot figure any way to do some debug to see if the device is being recognised or perhaps some low level gpio/i2c tests to check the hardware. config .txt and config-user.txt I think are set correctly.
Can anyone suggest anything else to try? A low level test of the card would be really handy.
Finally it was a few years ago I first set this up with the old OSMC install, but I seem to remember I had to do something specific with gpio settings. I could be wrong or maybe that's just an old trick no longer needed. I can find no reference to any such setting these days
many thanks in advance
