I have antergos and gnome as DE dual booted with windows 10.

Everything was ok until I powered on the laptop and played a movie, there was no sound.(Also no sound when headphones plugged)

There is sound in windows so its not a hardware issue.

Here are some system details:

System is fully updated and I tried reinstalling pavucontrol pulseaudio pulseaudio-alsa pulseaudio-bluetooth alsa-firmware alsa-lib alsa-utils

Nothing worked :( I like arch linux but it sometimes gets annoying.

    Try increase master volume. Jul 17, 2018 at 22:33

    This used to happen to me as well on older distro, the suggestion of turning up the master vol was always the solution.

    Also, if you use Pulseaudio and not only ALSA, start pavucontrol while your application is active, and check if it's using the correct output device, and if all volume sliders are high enough, and if none is muted.

Found this page following up post by Manjaro user with same Realtek ALC294
ALC294 Analog - Audio card detected, but no sound internaly or headphones

Also found this page from ubuntu user indicating cause of problem
No sound output - Ubuntu 17.10 - ASUS Zenbook 13

All 3 appear to be same problem caused by windows 10 shutdown

Web search results show no other Linux issues reported for ALC294; suggests this audio device working in Linux when not affected by windows

  • I didn't find what the problem is but when I powered off laptop from linux for some hours it just got fixed automatically.

I found that this problem is common in windows/linux dual boot systems and the solution for me was putting system into suspend mode by running systemctl suspend in linux system and when you get back everything is ok, sound is working again.


I have this issue in my laptop Dell Inpiron 13 7359, 7, with the sound card Conexant CX20722.

The module for pulseaudio/alsa is the snd-hda-intel, and in my case its running insert only the line below on the /etc/modprobe.d/alsa-base.conf.

options snd-hda-intel model=dell-laptop

There is a problem of conflict with windows partition.

Try this.
