Hi y’all, <\/p>\n\n\n\n
Today I am going to write up a project I am working on. <\/p>\n\n\n\n
Problem: I have a USB headphones with cat ears. The Mixers only output analog. Also Needs to be headless.<\/p>\n\n\n\n
Solution: Use a ADC and pulseaudio to convert it to a signal that the USB headphones can use. <\/p>\n\n\n\n
I used a Raspberry pi, a LCD board and a Behringer UCA222<\/p>\n\n\n\n
The UCA222 converts the analog signal to digital. then I am using pacat from pulseaudio to receive it then a pipe to send it to the headphones via pacat.<\/p>\n\n\n\n
Now for the headless part I am using the Adafruit 16×2 and button board to control the system. The system is controlled through a python3 program, that reads the buttons and does what is needed based off input.<\/p>\n\n\n\n
Currently I am having a issue of getting the script to start on boot. when it is called via crontab the system calls do not work, Looks like I get to deep dive that call.<\/p>\n\n\n\n
<\/p>\n\n\n\n
—-Update —- <\/p>\n\n\n\n
To get the script to work, I had to start up pulseaudio daemon. It appears that the daemon is started on login. since I am starting my program via crontab….
I had to build a quick bash script to spawn it and then kick off my python program.<\/p>\n\n\n\n
