Hidden channels are a lot more likely to break or be broken compared to devel. They're hidden from users because of that. Usually used by devs to test big things such as for example right now the 24.04 Noble images.

@CiberSheep said in How to set Calendar Reminder Sound Volume ?:

@AppLee it may be a bug. This doesn't happen anymore on dev channel

it works for me by setting via clock app, via uVolman, alert and alarm settngs have no effect for me and on Xenial too

With telnet I have see it is a mount failure.
On Telegram a man say to Put the .IMG file in data folder
I have put boot.img and ubuntu.img, but I think ubuntu.img is sufficient.

And now it work 😁
