My p10000 seems to have only one speaker working at the bottom or it is at half volume

When I used to turn the phone on it was very loud now I can hardly hear it

Is this a software thing or hardware?

Can it be fixed easily

It looks like an hardware fault, but to rule it out please perform a factory reset,  try again and report back.

No change with factory reset

It looks like an hardware fault. If you phone is still under warranty, please contact your seller to have it replaced or repaired without additional costs.
If your warranty ended, you can try to replace the speaker by yourself. Here you'll find the spare part:
