OK, there are some developments...
First of all, when browsing around I discovered this on the Tweaks page: 32642 I wondered if this had anything to do with things, so I tried activating the gpio-poweroff tweak (setting the pin to 13) and rebooted. But it didn't seem to do anything. I deactivated it, rebooted, and then to my surprise the Squeezelite power on/off started working (when switching the player on/off via the LMS web interface). Q: DOES ACTIVATING THE GPIO-POWEROFF TWEAK CAUSE SOMETHING TO GET SWITCHED ON IN THE PI HARDWARE? This was all using the Pi2. So I returned to the Pi4 only to discover that the same sequence of events did NOT cause the power on/off to start working. OK, so now on to Paul's suggestion: paul- wrote: > How many players do you have on your LMS, are you sure you are selecting > the correct player when toggling power? > > There are 2 command line tools provided with pcp. > > pcp-gpio (which will let you do simple things like toggle and output or > read an input.) > readall.sh (This is a simple shell script that reads the current state > of the gpio) > Yes, I am sure it's the correct player. It's the only one called "picoreplayer" in LMS :-) I played around with pcp-gpio & readall.sh, and confirmed that the pins are behaving as they should: readall confirmed that GPIO was in OUT mode "pcp-gpio write 13 1" sets GPIO13 to 3.25V, and "pcp-gpio write 13 0" sets it to 0V. This was verified by both the output from readall, and using my multimeter to check the voltage. But turning the player on & off in the LMS web interface didn't change GPIO13. The voltage shown on the multimeter stayed the same, and the V column in the readall output didn't change. This was on the Pi4. Thinking I might have imagined it working on the Pi2, I returned to that and sure enough the Squeezelite power on/off IS working when the payer is switched in the LMS web interface. (And just to verify things, it also worked when turning the player on & off using the Squeezer app on my phone). So it's all a bit perplexing.
