Ideally, you would find another way to get that audio out of the PC. The 1/8″ stereo mini jack on most sound cards have several issues that have been setbacks for me when I have tried to use them.
First is noise – the outputs aren’t well shielded and while typical uses don’t often suffer, I have had all kinds of problems with noise coming into the transmitter using the mini-jack.
The second is issue is mechanical connection quality – I’ve come home and tuned in my station only to hear nothing and after wiggling the jack plugged into the sound card the audio comes back – grrrrrr!
Last is impedance – goodness knows what the output voltage and impedance might be – some sound cards have line out jacks and other confusing options and some are jumper-settable on the card – it’s always a guessing game and lots of trial and error.
I’m thinking of trying one of these – good old RCA connectors and a better path away from all the noise
