From these details, it's certain that the microphone of your Lumia 520 is still working while the speaker is not.
Have you tried restarting your phone? Have you tried performing a soft reset? If you're willing to perform a hard reset, you may also do so.
If these three don't resolve the issue, then it's most probably hardware level - something that can be fixed by having the specific hardware component replaced.
