Allright, time for a update. I had a friend of mine successfully shrink the fat32 partition of the full 1.24 image a little, so it now writes to my 16gb card without any errors.
The good thing is that i have the two correct partitions, it boots correctly, and i have sound and access to the WebUI via LAN!
I do however have some minor issues:
1. I only have sound when using the Pi's default output. I have not been able to output sound through my USB sound card, which i was using on the previous versions. I have the use-usb.txt file on the new USB card that holds the sounds like this USBDRIVE/data/use-usb.txt - Perhaps that is the wrong place for it, or it simply isn't needed anymore?
2. Concerning problem 1 above: When i started testing i was able to access the WebUI's config page. But even if i used that page to set the sound device to USB, nothing changed (not even after a restart of the Pi)
3: For some reason i am no longer able to access the Config page via the WebUI. It is empty, and a red error is shown in the bottom of the page saying something like "A problem occured". The other pages of the UI seems to work as they should.
4: I am unable to use wifi, but i am pretty sure that is me not knowing how to configure it correctly via the dietpi and dietpi-wifi files. I'll keep trying
Oh and if you read this Steve, i had a question about adjusting the gain, ducking and individual sound volumes via the UI. Are those changes stored on the fly, or are they not stored at all? Because i don't see any way of saving the changes.
As always your work is extremely appreciated!
