OK, I bought 2 PHAT DAC’s.
I soldered the headers on and plugged one onto my PI3 with the Official Foundation display attached.
I burned a Raspian 5.27.16 image onto my 32GB card and put it in the pi.
I fired it up and went through all the raspiconfig stuff through the GUI. Wifi country, keyboard, time zone, etc.
I ran the script in the tutorial “curl -sS get.pimoroni.com/phatdac | bash”
I then ran it again and got the speaker test routine. I was only getting the “Front Left” audio. I found that I needed to plug the yellow instead of the red from my 3.5mm cable to RCA plugs into the right channel on my amplifier.
I went back and tried the original PHAT DAC, and it’s not damaged, I get the “Front Left and Front Right” sounds out of my amp now.
I copied an .mp3 file to /home/pi/music
I opened a terminal window and cd’ed to that directory. typing “dir” there shows my .mp3 file.
I then typed omxplayer “file name”.mp3. It looks like omxplayer is starting as it gives me some stats, but I hear nothing. I assume that omxplayer is not routed to the DAC, and I have no idea how to do that. I see that
“omxplayer -o hdmi example.mp3” will set it to HDMI and
“omxplayer -o local example.mp3” will set it to local (according to the www.raspberrypi.org/documentation/usage/audio/)
But since the PHAT DAC is now the output, how do I play my file?
