No sound

[Merz]

After upgrading to CFW 5.00 m33-4 my psp lost it's sound. It detects headphones being plugged in but I get no sound from them either. I've tried chaning CFW, bricked it once, put it on 1.50, then CFW 4.02, and I've still got nothing. Any help would be appreciated.

I seriously have no idea? Maybe it's your console, sometimes they lose their sound (dropped maybe?). Once I had a transparent GameBoy, which lost it's sound, though worked perfectly with headphones.

You should try GEN D3, though you would have to go through all the GEN firmwares to the point of GEN D3. I have no trouble with it.

Went to GEN D3 and still no sound.

I did notice that when i turn the PSP on with headphones in it makes that sound headphones make when they get plugged into something.

I think this may be your solution, even though the video has very terrible spelling/grammar.
