Troubleshooting Q&A and Support
Q: The LED doesn’t flash or light up when I insert it into a USB port.
A: FlooGoo FMA120 can be inserted into a USB-A socket from both sides, but it
only works when the correct side is used. Check if the golden connectors on
FMA120’s USB connector are contacting the receptors of the USB port when
inserted.
Q: Can I use the dongle with Raspberry Pi, smart TV and projector?
A: FMA120 functions as a standard USB audio device. With the latest version of
Raspbian, it is detected automatically. You can use command “aplay -l” to
verify if it has been recognized successfully. For Android-based smart TV or
projectors, please activate the developer mode and ensure that “Disable USB
audio routing” is not enabled.
Q: Do I need to keep the desktop app running to use the dongle?
A: No, you don't need to keep the desktop app running to use the dongle. The
dongle retains its settings, allowing you to set it up on one host and use it on
another.
Q: How do I enable the aptX codec, including aptX HD and Adaptive, when
using a compatible headset?
A: The dongle will automatically select the best codec when connecting to a
compatible headset, you can confirm the chosen codec in the “Codec in Use”
panel in the desktop app.
Q: I already have a standard Bluetooth adapter, will FMA120 conflict with it?
A: No, the FMA120 runs all its functions, including the Bluetooth stack, within
the embedded high-performance processors inside. It doesn’t require
additional drivers on the host, so it won't conflict with other Bluetooth
adapters.
Q: Do I need to reset the dongle to apply a new setting?
