Audio jacks not working on MintBox 3

Post by Andrey.Mazlin »

Recently a few cases with the same symptoms were received by us. Below you can find a link to linuxuprising site with a few solutions that can fix this problem. In general - problem is related to Ubuntu OS (Linux Mint is based on it):

The solution below solved the problem at least in one case:

#2 Fix PCI/internal sound card not detected (dummy output) with Ubuntu kernel 5.3.0-41 and -42 in Ubuntu 19.10 / 18.04

The solution for this "dummy output" regression is to:

1. Edit /etc/modprobe.d/alsa-base.conf as root and add options snd-hda-intel dmic_detect=0 at the end of this file.
You can do this with a single command, by using (run this command only once):

Code: Select all

echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
2. Edit /etc/modprobe.d/blacklist.conf as root and add blacklist snd_soc_skl at the end of the file.
You can do this with a single command, by using (run this command only once):

Code: Select all

echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf
3. After making these changes, reboot your system.
