Why is my microphone and upper speaker failing on my Lumia 925?

[Windows Central Question]

microphone and upper speaker failing lumia 925

My lumia 925 is behaving strange lately ... It started when people could not hear me when id answer my phone... Then it got fixed on its own , and after soms time , i noticed my videos are being recorded without any sound... Then , things likr shazam and cortana aint working cause they do not detect any sound... It also got fixed after few days , but starting today , i cannot talk via my phone , i cant hear anyone talking , nor my mic works on any app.. While i was posting this , someone called me and it seems fixed again ..but i really dont know how to do a permanent fix... Mic for video recording and voice recording still doesnt work , while i can talk in a call atm. I did many resets , and nothing...i also did a denim update yesterday , and no improovements ... (phone itself works insanely fast)Please help ? Thanks

This seems like a hardware problem, you might want to bring it in to check it out (to the store)..

Or if you want a DIY project:

You need new components And since you're not afraid to mess with your phone, you can order whatever you need online and install it yourself

Do you have a link where to buy the part?

Lumia 730
When I receive a call, I can hear the caller, but the caller cant hear me.
When I speak into the microphone, I hear myself after about 1-sec delay sounding far away (like a fading echo).

Any ideas to hep me out?

Thanks.
