If you can hear sound through the radio but the volume is still not adequate, the problem may be with the speakers themselves or their connections.
Conversely, if there is no sound at all, even when connected to a different source, it suggests there may be a problem with the radio unit. In this case, further diagnostics may be necessary. Inspecting the speakers visually for any signs of damage or checking for proper connections can also help narrow down the source of the problem.
