Hello
Im planning to interface an YM2149 SSG with my Arduino. I've found some information about it here: http://kalshagar.wikispaces.com/Arduino+and+a+YMZ294 and YMZ294で楽しむPSG音源 (you might want to translate the second url with google translate).
Altough, both projects are using an external speaker. I want to be able to get the output on line level so I could just plug it in my sound card or any other amplifier. I'm not really sure which parts I need to make it line level. Any ideas?
