Audio Fix For Gigabyte B550i Pro Ax Mobo

Support & Help Requests
#1

ALC 1220-VB is giving problems again. As is, you will get audio from the line-out jack but only for one side (no sound from right speaker). Here's a fix that I made;

  1. Install alsa-tools-gui

$ sudo apt install alsa-tools-gui

  1. Open hdajackretask (admin)

$ sudo hdajackretask

  1. Find Pink Mic Rear Side and click Override. see pic below

  2. Also, over to the right side under Options, click Advanced Override. Change these

  • Device category to Speaker
  • Channel (in group) category to Front
  • Channel group category to 3 (or 2 if you don't have subwoofer)

855×837

  1. Click Install Boot Override there should be a popup saying that you should reboot. Reboot and test the speakers.

Note: I tried to override the Line-In Jack but there was a lot popping. Mic jack is stable.
