unusual noise from soundcard input, even when muted.
I recently started to use my internel sound cards inputs to record audio. and have noticed that there is an unusuall noise floor. its very unbalanced aswell, having a significantly higher level on the right side than the left. even with the input level set at the min for the sound card its still present. this noise isnt audible.
its also still present if i mute the input.
if i load jamin and rout the input into jamin to look at it with the HDEQ, it shows up as very low frequency noise. the highest level revestering at the lowevst frequency which is about 25hz which tails of to about 30hz.
this recordings look biased towards the right side even though they are coming in dead centre from the source. playing back recordings also shows this bias to the right.
Is this system noise? or just due to the poor built in sound circutity of my cheap motherboard. its just weird that this noise is still present even when muting the line inputs.
the exact same noise is still present if i switch to the mic input.
