As far as I am aware the pi zero doesn’t have audio unless you add something like the Phat DAC. This means the amplifier on the Picade board will not have an input and could pickup stray noise hence why you hear buzzing.
Buying Picade was my wish for some time now, Saw the weekend birthday discount and went with it. I got the Pi Zero for free in the package and since I do not own Pi2 or Pi3 I wanted to try it with that. If Zero has no sound then it makes sense about the noise and the no sound issue.
I have ordered Orange Pi PC some time ago and it should arrive soon. Can that device work with Picade?
Wife was not happy of me buying Picade so adding extra 40 € to the purchase is something not discussable with her. And I got the Orange Pi PC for 8 € few weeks ago on a sale.
Audio is not at all connected. I hoped it will work over HDMI. Pi Zero has no 3.5mm headphone output. Reading the specs it says that the digital audio works over HDMI. So if Picade screen does not connect to the speakers it makes sense that I have no output.
I have also updated the Picade firmware in SSH and the buzzing humming sound is gone. Even if I change volume with the keys to maximum, speaker are completly mute now.
I will test it with my Orange Pi when I get it.
About 12.1’’ screen. Where can I get the black carton border for it if I decide to purchase it?
Bless you man. If she finds out how much the 12.1 inch screen cost good luck with that. My wife hates my picade too. It’s like my picade is a girlfriend or something. Funny how they are if you enjoy something they don’t have to do with that makes you happy. I measured and cut out the 12.1 shim out of the 8 inch one that came with the picade.
Ask her how much she spends on makeup, shoes and clothes. The cost of makeup will increase exponentially with age. Don’t try to tell them that learning and being at the cutting edge of technology will only get you better jobs and more money she can spend. I don’t know how I ever bought an Altair 8800 (w/ 256 BYTES RAM) in 1975 after a year of marriage. That got me a better job and it kept going up.
Remember a wife is there when you need her, but she is also there when you don’t. Keep your own money and buy what you want. Mine could smell something new “Japanese?” no, Korean Colour Monitor. I would still be using a TTY or binary toggle switches.
