Power Mac G4 mdd audio input works like crap

I was just wondering if the powermac g4's had any kind of audio input quirks. I have a mic that I was trying to use to record some stuff, but the computer will only pick up sound when i hold the mic a certain way. I guess i was just wondering if this is just a g4 quirk and if there is a remedy for the problem. oh yeah its not a usb mic, it's just one of those mini jack things if ya know what i mean. Let me know. Thanks in advance

could just be a bad input plug, or mic wire. i have a g4 733 digital audio, so i went ahead and got a 24/96 pci card. been working great for over 7 years.

p.s. its a bit pricey but you have RCA in/out, digital in/out and a MIDI dongle.

this is a newer version of what i have:

Doc MDD G4 require you use a self powered microphone connected to the input port. here is a link to this:-

I would do as the previous post suggests as G4 audio is pretty basic.

yeah, i didnt understand that my machine didnt have a line-in when i bought it. (learned later that you had to use USB audio). but im really glad that i bought my sound card. its very versatile and gets a really clean 24 bit signal. paired with a decent little mixer and ive got a nice little home studio that can produce "bigger studio" quality recordings.
