Hey lads

When i plug a signal cable from my Roland MicroCube to my LINE IN (I have an external dedicated sound card btw so should be fine) the output is very low and i need to crank up the recording volume max to hear it but there is horrible static bursts.
I then try to use MIC IN, no volume problem here and all in all better (which I don't really understand, shouldn't LINE IN be preferred?) but still static bursts.

I used Audacity for recording and it was mainly in R-FIER settings (max gain - metal setting)

Anyone knows how to fix this? New signal cable perhaps?
