I have used the Volt 476P without issues for months, but now a problem occurred overnight:
When trying to record bass/guitar, Logic only receives silence. When I turn the gain all the way up, bits of artifacts are recorded. I can monitor what I am playing through the soundcard just fine though.
When recording with microphone, everything gets recorded, and seems normal.
I have tested input 1 to 4, but the problem is alike on all channels.
There is nothing wrong with the cable, or instruments.
What can cause this issue?
Logic Pro 10.8.1
macOS 14.3.1
