I got a Line 6 gx recently. everything seems to be hooked up correctly. The software is installed and registered. All drivers are installed. The gx is registered. Monkey shows green ticks. I have the Line 6 selected in my Windows sound system. I can hook up my headphones to the Line 6 box, and run a windows sound test, and get sound. I can connect the guitar, and start pod farm 2. When I hit the strings, I can see plenty of output on the meters. I can use the tuner in pod farm and tune the guitar. But I get absolutely no sound from the guitar. Not in the headphones, not frim the laptop speakers. Is there any additional software that need to be installed? It is a Lenovo thinkpad laptop, running windows 7 Any suggestions?
