Kegan Simpson Posted December 25, 2019 Posted December 25, 2019 Hello. I'm writing a program that requires sound.target. I was reading about sound.target and how it's a special systemd unit that doesn't load until the system finds the sound card. Armbian takes quite a bit of time to find the sound card on the OPi, around 30 seconds. Or, maybe it's something else that's making it take so long. I was wondering if there was a way I could mess around with systemd or something else to make the sound card found faster, thus sound.target and my program loading faster upon powering on the device. Thank you

If you want such severe changes, you need to make a totally custom Linux OS from scratch with Buildroot or Yocto. Which will ofc cost you a lot of your resources ...
