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 (https://bugzilla.kernel.org/show_bug.cgi?id=205959)
Solution:
- 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' .. done
$ 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
