Okay here's the thing, N900 won't want to play anymore sounds, I don't know why but it doesn't.

How it's acting:

Well I open media player, select a track press play and nothing happens. Playback doesn't start withing the player (meaning seconds don't pass) and no sound output.

I tried using headphones, no sound, no playback

I tried using bluetooth, no sound, no playback

I tried using FM, no sound, no playback

Used another media player, no sound, no playback

Then what I did:

Reflashed device, tried again every step that I wrote before, nothing

Reflashed emmc and then firmware, same problem

Checked every connections on the motherboard, nothing

Cleaned again every connector, nothing

Other problems this phone have: broken GSM chip.

Thoughts on this?
