No sound whatsoever after trying to fix crappy sound

I run an unpdated Manjaro I3 Linux from an USB card (can’t install on hard drive due to it being a business laptop, but I can boot from USB and it’s not a live distribution: it’s a complete installation). This Linux version has been installed specifically on the machine I use, so driver-wise we should be fine, but alsa had all sorts of bizarre behaviors. Sometimes the sound just wouldn’t work, other times it would work but have a very grainy quality, it was horrible. So I followed a few guides online, suggesting to install pulse, uninstall alsa, no wait, install alsa, but add this kernel parameter on boot, never mind that, remove the parameter, reinstall alsa. And voila’, within 5 minutes, the sound just stopped working. All I can understand is that now alsa thinks that my sound card is not compatible and the list of sinks available is EMPTY.

I think I have undone every single step - beginning of course with removing the extra kernel parameter - but the audio now just does not work. I spent hours on this and I am at the end of my wits. I hate how stupidly convoluted the sound system is on Linux, alsa and pulseaudio and all of that crap. I have used Linux for over 20 years and the audio system is still a black box to me. Please help.

Hey @darioshanghai :wink:

At least you could start with some value information:

sudo inxi -Fazy

Please… use markdown for formatting the code like this:


I get eye cancer from this above. :slight_smile:

Many apologies for your eyes, didn’t understand the editor. Fixed, hopefully. Here is the command you asked:

I guess you are one of the lucky ones who are able to use the sof-firmware: Platforms — SOF Project 0.1 documentation

  1. Install sof-firmware
  2. blacklist snd_hda_intel and snd_soc_skl if needed
  3. Make snd_sof_pci load first.

The reason for not loading snd_sof_pci is maybe because of the kernels decision to load snd_hda_intel first, because it has wider support than sof. On newer Kernels than 5.4 it should use sof first.

Here for example on kernel 5.10 it loads snd_sof_pci first:

But well, the sof-firmware was not installed and sound did not work because of this.

Well, we have progress! I could blacklist those modules, and it loaded sof-audio instead. Unfortunately we’re still silent, and we still seem to have no audio sinks.

Should I try and update my Kernel? I am happy with the Stable version, this is the only issue I have. Or else, what?

kernel v5.4 does not support this type of digital array microphone and sof-firmware

Device-1: Intel Cannon Point-LP High Definition Audio vendor: ASUSTeK 
  driver: snd_hda_intel v: kernel alternate: snd_soc_skl,snd_sof_pci 

kernel support for sof-firmware was only added about 12 months ago with kernel v5.7 and later

so you should go Manjaro Settings Manager

manjaro-settings-manager -m msm_kernel

and install kernel 5.10.4-2

and also remove any blacklist options that may have been added before

When you boot system with new kernel, it should load snd_soc_skl instead of snd_hda_intel driver and internal microphone should work

Simply blacklisting didn’t work. Had to update the kernel as suggested, and then the blacklisting became unnecessary. Sadly, the quality of the sound is still far from ideal.

Thank you folks!

Two things that may help improve audio quality

1 - PulseAudio only runs at CD quality (16bits @44100Hz) by default, for backwards compatibility to old hardware.
But modern hardware can support DVD quality audio (24bits @48000Hz)

to reconfigure PulseAudio for DVD quality, copy this whole code block to terminal

cat <<EOT > ~/.config/pulse/daemon.conf
resample-method = speex-float-3
default-sample-format = s24le
default-sample-rate = 48000

then restart PulseAudio

systemctl --user restart pulseaudio

to check if the new configuration is in use and settings have been applied

pulseaudio --dump-conf

2 - You may want to Install pulseaudio-equalizer-ladspa to add some boost bass for audio to laptop speakers
