What is better sound with HDMI screen ?

Post by Marty33 » Thu Jul 19, 2018 1:54 am

Hello all.

I use this famous KEDEI screen. And i use Tinkerboy v.1.1AIO .

I discover new diagram for use jack sound on the screen motherboard.

In my plan, i going to use PWM>low pass filter>pam8403 amp.

But if the jack solution is better, i can gain place in my Gbz.

Thanks for your help 😉

replace the USB sound card, with the Headphone jack on the Kedei screen and you'll be good.......
(the Kedei Headphone socket route is going to sound better than PWM)

i've used this method and it worked perfectly for me.....


if using any type of board, just wire the system accordingly
in order

sound source (HDMI screen board, USB Sound Card)
Volume Wheel
Headphones
Amp
Speakers

resistors can be added (to the speakers) to reduces any static or interference (but not necessary)



just my suggestion (based on my builds), other may have other solutions
