Good morning,
I use Volumio with Roland UA-S10 interface. It works great, except for one option. When I use the button, the program locks up. I have to do a restart to get it working again.
Please post a log so we can check which drivers have been loaded by the kernel.
The UA-S10 has not been added to the Linux kernel by Roland, so i expect the kernel loaded a different driver causing this behavior. If Roland doesn’t provide drivers there is not much Volumio can do.
