A voltage excess will probably damage your board. My recommendation to you would be to follow the power specs of the datasheet. Take a look at section 5 to see the ways for powering the Edison https://communities.intel.com/docs/DOC-23158 . Also, if you are using an expansion board you can check section 4 of the guide https://communities.intel.com/docs/DOC-23161 to see if the power specs of the expansion board fit your needs better.
I beleve it will not tolerate 5v and you will need a 4.5V supply or lower. Sparkfun's Console board outputs 4V to the Edison VSYS.
I'm interested in getting sound on the Edison as well so I was wondering what DAC you are using?
Thanks @Intel_Alvarado and jmp246
So, How create power supply dual output DC 5v and 4v? It is not findable on Aliexpress or another, no ?
And this DAC is powered since usb but i will have removed usb (because for production i will use I2S), so how powered is without usb connector ?
