I read that the FBV Express MKII can be used to connect your Windows 10 laptop/computer to your Line 6 amp (mine is the Spider Jam)., but the article didn't say how to set it up. I want to be able to use an online tab player, like those found at sites like 911Tabs and Songsterr, to play tracks out of the amp so I can mute the guitar parts and play them myself. I was using a regular 3.55mm audio cable in the headphones jack on the laptop, and the CD/MP3 jack on the Spider Jam, but it was a cheap cable and each end broke off inside the equipment, so that option is no more. When I connect the MKII to the amp with the cat5 cable, the controller powers up and works correctly with the channel presets installed on the amp. But, when I connect the laptop to the MKII, with a 2.0 USB cable, it switches to USB Mode and the channel presets no longer work (but I can still get sound from my guitar). Thinking I was golden, I loaded up a tab player, selected a song and clicked play. Nothing. No sound output at all. If I unplug the USB cable from the laptop, I get sound out of the internal speakers. Plug it back in and nothing. I've tried about a million different sound/driver/USB/ configurations and nothing worked. I'm starting it think it can't be done, and that the MKII is only capable of playing pre-loaded tone configs built into the Spider Jam (MKII and amp), or performing hands-free functions of 3rd party audio applications (MKII and laptop). Can anyone confirm/deny whether routing sound from the laptop, through the MKII, and out of the amp can be done?
