Fix audio not working on Ubuntu 24.04.3 (at least in my case)

#audio #ubuntu #linux #earphone

Recently I installed a new Ubuntu, after that my wired earphones didn't work anymore, I spent a lot of time fixing it. Here is the step that I did. It might depend on the device; in my case, it is an Asus ROG Strix.

Step 1: Check if the device is detected

Run

lspci | grep -i audio
Enter fullscreen mode Exit fullscreen mode

You should see something like:

00:1f.3 Audio device: Intel Corporation CM238 HD Audio Controller (rev 31)
Enter fullscreen mode Exit fullscreen mode

If nothing appears, your kernel might not detect it → you may need firmware support.

If it does appear, continue.

Step 2: Check sound card listing 

aplay -l
Enter fullscreen mode Exit fullscreen mode

You should see something like:

soundcard-listing
If you see “no soundcards found”, try:

sudo alsa force-reload
Enter fullscreen mode Exit fullscreen mode

then check again.

Step 3: Open sound settings 

pavucontrol
Enter fullscreen mode Exit fullscreen mode

Install if missing: sudo apt install pavucontrol

Step 4: Reload ALSA and PulseAudio 

sudo alsa force-reload systemctl --user restart pulseaudio
Enter fullscreen mode Exit fullscreen mode

If you use PipeWire (Ubuntu 24.04 does):

systemctl --user restart pipewire pipewire-pulse
Enter fullscreen mode Exit fullscreen mode

Step 5: Check kernel module

Make sure the driver is loaded:

lsmod | grep snd_hda_intel
Enter fullscreen mode Exit fullscreen mode

If missing, try loading it:

sudo modprobe snd_hda_intel
Enter fullscreen mode Exit fullscreen mode

Then confirm:

dmesg | grep snd_hda_intel
Enter fullscreen mode Exit fullscreen mode

Look for errors like:

cannot find codec # or device initialization failed
Enter fullscreen mode Exit fullscreen mode

Step 6: Fix possible model issue

Try editing ALSA config:

sudo nano /etc/modprobe.d/alsa-base.conf
Enter fullscreen mode Exit fullscreen mode

Add this line at the end

options snd-hda-intel model=alc295 options snd-hda-intel model=auto options snd-hda-intel model=dell-headset-multi
Enter fullscreen mode Exit fullscreen mode

add-model

then reboot

For me, it works
