Hi guys, I'm brand new here.
Be advised I know very, very little about sound and recording and I'm trying to record some drum covers for my youtube channel.

My situation is: I have an ipod playing the original audio and me playing my electronic drums over the top.
I plug my ipod into my mixer's first mono channel using a cable with a headphone jack on the ipod end and a headphone jack with a quarter inch mono adaptor on the mixer end.

(It's a very cheap Behringer Xenyx 1002FX mixer.)

My electronic drum module outputs to the second of only 2 mono input channels on the mixer (in both cases I'm using the quarter inch pluginstead of the big XLR one and turning the gain up quite a lot). This cheap mixer has more input channels but they're stereo, don't have an XLR port and don't have gain.

I output from the "L Main out" to a Powered P.A. mono speaker (Behringer B215A). This works out OK because the ipod's input is converted to mono from the quarter inch adapter so I hear both channels on the one speaker and my electronic drums give a mono output too.

I output from the RCA "CD Tape Out" using a stereo RCA cable which goes to a headphone jack...with an extension cable eventually reaching the microphone input on my computer (the red jack on my on board sound card). I have the microphone boost enabled on the Realtek HD sound panel software.

Believe me I've tried all sorts of other solutions and this is the only one which gives reasonable results - in the past I've tried playing with a mixture of electronic and acoustic drums/cymbals and this is so loud...I hate trying to monitor the original music on headphones turned up really, really loud and then blasting my drums over the top (this is very neighbour unfriendly and when I can't hear a clean mix it's hard to keep in time with the music).

So given what I've said - can anyone see anything I'm doing wrong? So far this is the only solution I've found which results in a pretty clean mix being output to my P.A. for monitoring and Computer for recording and gives a reasonably loud result which when played back, comes out of both left and right speakers on my computer.

My final question - the result I get is a bit fuzzy and low quality (obviously I'm using lots of cheap gear, plug adapters etc. and my setup is very budget and far from ideal but if I were to upgrade anything what would be best to spend money on? I'm interested in a new sound card because this on board one doesn't have "Stereo Mix" and I need that for something unrelated.

Thank you in advance for any help you can offer.
