Well that’s torn it!
It doesn’t work at all now.
I did the following … Under Audioplayer, I clicked Edit Advanced Options and I added the „hw:0“ to the command line options. That failed so I tried „hw:1“. That failed. So I removed it so that command line options were blank as they had been before the changes. I rebooted but still no sound at all.
So I selected ‚Reset configs to Max2Play delivery configuration‘ from Settings/Reboot and then rebooted. Still no sound!
Any ideas ?
