okay i want to trigger my basedrum for some recordings

Please, don't take all that i say for granted since i just started my electrical engineering this autumn,
but, that's my answer with what i know on the subject.

On that circuit, nothing reduces the input voltage.
If your sound card spec says that it can take a 9 volt impulse... it's ok

If i base myself on my sister playing electric guitar onto our computer sound card to record herself(i didn't know she was about to do this)
well... it did %$?%$?/$%?/$%?/$%?/$?% and stopped functionning.

Tbh, i don't think a sound card functions on 9V but... we never know... i don't know much on those.
But i'm pushed to say that computer speakers don't send that 9V voltage.

you shouldnt feed bias or phantom voltage through the same conductor as your audio signal. It will distort the hell out of ur sound. If you must put them both on the same conductor you can use a blocking capacitor in order to block the voltage signal from passing through to the actual sound card just connect it in series after your trigger.

Even without understanding exactly what you are trying to do or your exact specs... that just looks like the beginning of a bad day. O_o

Can't you just mic it and do whatever you want with the software?

That doesn't actually make any sense, IMO. You might have been using the wrong kind of mic, though. There are specifically made drumset mics that you can buy and it comes with a set of 8+ mics that are specifically made for snare/bass/cymbals/toms etc. If you use a vocal mic, you could have bad results just from that alone because they're designed to capture sound differently than the drumset mics.
