  6. Hi, David,
    The consensus among reviews of the LE Pro 3 is that it has FM radio capability. However, I do not see any chip mentioned in your article that supports FM radio. In your teardown did you find any such chip? I’m trying to build a kernel and support into Lineage-15.1 that supports FM on this device, but I don’t know which chip does the FM and so which driver and firmware to build in.
    Thanks!
    -Warren
