Symptom: No sound from both Front and Rear analog audio outputs

1. Possible reason: There is a audio bug in kernel 5.4 you may encounter on your Airtop (


  • On Airtop in Linux both "Rear Audio" and "Front Audio" can not work in the same time
  • By default enabled "Rear Audio". If you want to switch to "Front Audio":
- Press [DEL] during boot to enter the BIOS settings
- BIOS -> Quick-Settings -> Rear/Front Audio -> [Front Audio] or [Rear Audio]
- Press [F4] Save and Exit
  • Open file /etc/default/grub for editing
  • Add "snd-intel-dspcfg.dsp_driver=1" to the end of kernel boot line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd-intel-dspcfg.dsp_driver=1"
  • Update grub settings
$ sudo update-grub2 
Sourcing file `/etc/default/grub'
$ sudo reboot
  • Test audio output
Menu -> Sound -> Output -> Built-in Audio Analog Stereo (it's not dynamic, nothing changes after plug/unplug headphones)
Click on "Test Sound", then on "Front Left" and "Front Right", check if it hear it from headphones
