Electronics and water do not mix. You can try to turn the volume up, Turn the ring volume up, Try using it with headphones or wireless headphones, Almost anything can be fixed, but at what cost? If the simple things do not get results, there is probably an internal problem, sound amplifier, speaker, switching, or control.
Most internal problems would near or exceed the cost of replacement, Sorry!

It seems that your phones internal speaker is not working. You should get it replaced. But for the time being, yes you can use the loud speaker.

it seems the internal speaker of your phone is not working..
most probably music will play as it is using different speaker than speaker used for calling.

so try to get the internal speaker replaced and see if it works.

Plugging-in a set of headphones to the "audio-out" port *SHOULD* cause the internal speakers to become QUIET.

Unplug the headphones, to make the speakers work.

Protect mode will kicking whenever a fault is detected.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Connecting headphones to the system will disabled the internal speakers until the headphone jack is disconnected, at which such time the internal speakers should function again.

If you disconnect the headphones and the internal speakers are not re-activated, then there may be damaged to the microswitch in the jack. (Try rebooting after the headphones are disconnected too)

its might be muted look trough its options if not try to change new intern speaker its easy u need a soldering kit and a fit internal speaker.

If you can hear audio through the headphone jack but not the internal speaker jack, then the speaker is bad.

This is a problem I have seen many times before. I will be posting an article soon on how to replace the internal speaker, however this is not a repair that just anyone can do.

You have to have skills in dissassembly & soldering.
