Sound card not detected on Fedora 40 (Kernel v6.9.4)

[shivanksharma]

Hello,
I have a fresh install of fedora 40 GNOME (Kernel v6.9.4) on my new acer swift go 14 SFG14-72T
with intel ultra 5 processor. I am a newbie to linux and I am facing problems with sound on my machine. No sound would play through my buildin laptop speakers and gnome settings would only display “dummy output” for an output device…

It appears that somehow my soundcard was not detected. Bluetooth is working fine and sound is fine in windows ( as i am dual booting fedora and windows).

Can someone help me out with this. Tried to solve it using various other posts and disccusions, but no luck.

Here is the output from some relevant commands (I hope):

$ aplay -lL
null
    Discard all samples (playback) or generate zero samples (capture)
pipewire
    PipeWire Sound Server
pulse
    PulseAudio Sound Server
default
    Default ALSA Output (currently PulseAudio Sound Server)
aplay: device_list:279: no soundcards found...

$ lspci -v

Tried modprobe snd_hda_intel and reinstalled kernel modules as suggested by some posts. Pipewire and wireplumber both are up and running.

If you need any additional info just ask me.
Any advice greatly appreciated.

pulse
    PulseAudio Sound Server
default
    Default ALSA Output (currently PulseAudio Sound Server)

Do you b y chance have pulseaudio installed.?
If so then the above shows the cause. You appear to be using pulseaudio for sound when the default is pipewire and pulseaudio is not installed by default. They can and often do conflict.

[shivanksharma]

I tried pulseaudio to see if it solves my problem. So i removed pipewire and installed pulseaudio. But nothing changed, still no sound. I removed pulseaudio and reinstalled pipewire.

$ dnf list installed pulseaudio
Error: No matching Packages to list

Now i do not have pulseaudio installed. I tried to change default alsa output but was not able to do it. How can i do it?

[computersavvy (Jeff V)]

I suspect you still have some pulseaudio packages installed. Some are used by pipewire.

$ dnf list installed *pulse*
Installed Packages
gvncpulse.x86_64                                                     1.3.1-5.fc40                                          @anaconda

this is from my f40 VM that has never had pulseaudio installed.

I got

I removed alsa-plugins-pulseaudio and now default alsa output shows pipewire server. But still no sound cards are detected. Should i delete all of them??

Can you give us “pactl list short sinks”

[shivanksharma]

$ pactl list short sinks
bash: pactl: command not found...
Failed to search for file: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Could not activate remote peer 'org.freedesktop.PackageKit': activation request failed: unit is masked

i don’t have pactl probably because I am not using pulseaudio. Should i remove pipewire and install pulseaudio?

[ledeni (Igor Bezrodnik)]

no something is wrong

[ledeni (Igor Bezrodnik)]

sudo systemctl unmask packagekit.service
sudo systemctl start packagekit.service

[shivanksharma]

Ran the commands. But still no sound output. What should i do?i

[ledeni (Igor Bezrodnik)]

that is ok run pactl list short sinks

[shivanksharma]

$ pactl list short sinks
49	auto_null	PipeWire	float32le 2ch 48000Hz	SUSPENDED

Got this. It installed pulseaudio-utils, is it okay??

[ledeni (Igor Bezrodnik)]

ok run pactl list sinks
