I'm relatively new to all this so please bear that in mind - thanks.
I have a Hifiberry DAC2HD running on a Pi 4 and playing audio through my hifi ampllifier and speakers - all works well with the HifiBerry OS.
I bought a Pi 7 inch Touchscreen with the objective of using the Rune OS to replace the HifiBerry OS because I liked the Rune UI - BUT I can't get any sound at all out of either the h/phone socket or the DAC.
I've set it up with the I2S DAC2HD option - and I've checked the config.txt (which shows dtparam=i2s=on and dtoverlay=hifiberry-dacplushd) and I assume that it's all set up as it should be - but there's no sound. What else do I need to do???
Also, I am trying to login to the Rune OS with ssh BUT all I get is "Permission Denied - Please Try Again" I've tried the "rune" password and many others (using the IP address - email@example.com) but I cannot ssh into the OS - why is this?
And another quirck - I keep losing the Volume Control off the UI - I can set it up again and it stays there on the UI until I go into the settings menu again and when I go back to the UI, the Volume Control is missing again. This doesn't happen when I'm not using the DAC - i.e. I've not selected the I2S DAC and am just using the headphone.
I would be very grateful for any pointers on this - I've come to the limit of my knowledge (such as it is).
