finally i got my RB751U-2HnD in my hands , but unfortunately it not have an internal speaker, is is possible to install (solder) a mini pc speaker on it? Thanks in advice!

What?!?! No speaker!?!?!?!

im pretty sure the ones given away at MUM have speakers in them ... i was playing the super mario theme song someone developed on mine.

i'm pretty sure there is no onboard speaker! i will upload some pics soon

the black square is the speaker...

i tried with : beep frequency=2000 length .... etc but no effect? i tried the super mario theme script from mikrotik wiki it works on rb433 with 5.8, but on 751u i cant hear anyrhing

here the promised pictures

ah I mixed up the boards, to many models; this like rb750/rb750g\rb750gl doesn't have a speaker
