• Popping/Crackling sound (and NO audio) HDA-intel ALC295


    Just bought a Asus Zenbook 3 UX390UA with HDA-Intel ALC295. And trying Antergos for the first time. At first I was having problem with the speakers aswell, they where either muted or on highest volume. I fixed that issue, following this: https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX390

    BUT, there is still no audio when trying to use headphones. Only crackling/ popping sound. I have tried:

    Create and save a script in /usr/local/bin:

    #!/bin/bash
    hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x67
    hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000

    as mentioned here: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1648183

    I need to be able to listen to music throu headphones while studying! This is a dealbreaker! I’m so sad, I really liked antergos.

    Is there anyone else expieriencing this problem? Or better up have a solution?

    Do you have hda-verb installed?
    And you need to run your script as root!

  • @joekamprad Thanks for fast reply!

    I tried format the partition with Antergos on it (from win part) and reinstall Antergos. My headphones worked immediately, but same issue with the speakers (either mute or highest volume) so I did as mentioned here (again): https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX390

    After that the only issue was that the max-volume was very low, but I changed that in alsamixer.

    I have No idea of what the problem was or what fixed it, I’m just glad everything works!

    The problem is back after I booted into windows and then back into Antergos again…

    I have hda-verb, creating alc295fix.sh in /usr/local/bin with

    #!/bin/bash
    hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x67
    hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000

    run it with bash /usr/local/bin/alc295fix.sh

    Not working…

    Also the overall quality of the sound from speakers is now lower. Noiser etc.

  • run the script like this:

    sudo chmod -x  /usr/local/bin/alc295fix.sh
    sudo  /usr/local/bin/alc295fix.sh
    

    and may try to install alsa-firmware and reboot.

    This behavior that booting into windows and back into linux change something on hardware is a common thing, and mostly has to do something with buggy hardware, fixed by bad code under Windows drivers…

  • @joekamprad Thanks for all the help!

    when I’m trying

    su
    /usr/local/bin/alc295fix.sh 
    

    I get Permission Denied. And when I try

    sudo /usr/local/bin/alc295fix.sh 
    

    I get command not found

  • sudo bash /usr/local/bin/alc295fix.sh

  • but to see if the commands working you should try them without the script:

    sudo hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x67
    sudo hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000

    did it, and also installed alsa-firmware.

    The problem remains.

    sudo hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x67 
    nid = 0x20, verb = 0x500, param = 0x67
    value = 0x0
    
    
    
    sudo hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000
    nid = 0x20, verb = 0x400, param = 0x3000
    value = 0x0
    
    
  • @alge i was starting with a article here on investigate to soundproblems:
    https://antergos.com/wiki/hardware/getting-informations-on-soundproblems/
    I can take a look on it when i have time now i need to do some offline stuff…
    you can provide this one:

    wget http://www.alsa-project.org/alsa-info.sh && sh alsa-info.sh
