Card 0: Donât know what that Nvidia thing is
Card 1: Is my Tascam 16x8 USB Interface
Card 2: Something âGenericâ probably on the motherboard, never used that
Card 3: MS2109 is 1 out of 2 Capture Cards for live streaming
Card 4: Must be my Scarlett 2i4 USB Interface
Card 5: MS2109_1 is 2 out of 2 Capture Cards
Update for my situation so far:
I figured out that I got no I/O with ALSA backend because the Input and Output Device were set to HD-Audio Generic. When I select my Scarlett 2i4 USB as Input and Output Device with 48kHz 256 Samples Buffer size and 2 Periods, it crashes, means it is Running for couple of seconds and then Stops itself. With 3 Periods however it seems to be running stable.
My new problem now is that I only get 1 device as an Input Device but when I record drums I need 2. Is that even possible with ALSA?
By the way:
Thanks guys for the time and help. This audio thing really isnât an easy journey, so I appreciate your efforts to help and bear with me.
