Hi welcome to emutalk! Thanks for the detailed info on the post it should help someone to maybe offer more assistance what version of java do you currently use? Also have you tried checking the jcpsp site for other users having the same error? If I had to guess, it looks like a microphone issue but I am not sure of that
A general tip is to make sure you are using 32-bit Java rather than the 64-bit Java package, even though your CPU supports 64-bit. JPCSP has problems with the 64-bit version of Java right now.
