Why does my bass not provide enough gain for my audio interface?
I bought a used bass some time ago to teach myself some basics and have fun. I don't have a dedicated bass amp so I play it over my audio interface (Behringer U-Phoria UMC22), DAW (Reaper) and PC speakers.
Problem is, even when maxing out both the gain on the bass itself and the interface instrument input and also plucking the strings pretty hard, I'm still not even close to maxing out the meter in Reaper. I can scale up the signal digitally, of course, but this results in a LOT of unpleasant noise. The 9V block battery the bass contains is freshly replaced, so it probably can't be the issue.
I'm just starting into the whole electric music category, so I don't know a whole lot about it. Is a bass even meant to be plugged directly into the instrument input of an audio interface? Or do people normally put their bass amp (which I don't own) in between the bass and the interface to ramp up the gain? Could be anything wrong with the bass itself (other than the gain issue, it sounds fine and looks fine on both the outside and inside, as far as I can tell)? Or is it just normal equipment behaviour and I need to put up with it?

From the information you provide, it seems that your bass is already fitted with a pre-amplifier. It is thus giving a line signal.
On your sound card, the Mic/line input (which is a combo input that can accommodate XLR or Jack) is low impedance input and thus will have a better impedance matching with the pre-amp of the bass and might give you more juice than the second input which is meant to receive signals from passive (high impedance) instruments such as normal electric guitars.
You can try on the Line input to see if you get more signal, it should be more coherent to plug it there (beware not to have phantom power activated).
Another point is, if your signal is strong enough compared to the background level, this should not bother you for recording as you can very likely push a bit the gain inside Reaper while keeping a good sound quality!
