Realtek ALC256 In HP All In One PC

Hardware Support
1

I have an old 2017 HP 24-g080na all in one PC with Zorin installed latest updates.

The hardware all works flawlessly apart from the Realtek audio where only the right speaker works on quite a low volume and the left doesn't.

This was originally a Windows 10 Home PC and of course the ALC256 audio worked perfectly fine and is actually pretty loud and punchy.

My Dell AIO PC from 2015 running Zorin has Realtek audio and various other Realtek components all function out of the box, absolutely no issues.

The same applies to my series 7 Samsung laptop from 2012 which features Realtek hardware which all functions 100%.

This is the only Realtek driver issues I've encountered, has anybody successfully fixed the ALC256 issue?

In addition to Nourpon's advice re Pulse Audio.

Fire up alsamixer in terminal.
Ctrl+Alt+t

alsamixer

Hit F6 to list soundcard/s.
Select analogue card option if visible.

Hit F5 to show "All" channels. (post a screenshot would be good)
Check if both L&R speaker channel volume are set to same volume level.
Check [Automute] and [LoopbackMode] channel settings. try setting = disabled.

Welcome to the Forum!

Are Secure Boot and Fast Boot in BIOS disabled? Does Zorin run in Wayland or X11? You can check that with echo $XDG_SESSION_TYPE

Hi, I've tried the above and many other methods no luck. I guess it'll just be a case of waiting until the linux kernal is updated with fully driver support.

Hi and welcome. Zorin 18 is a fork of Ubuntu 24.04 which I used as part of criteria in Brave A.I. search result via Mojeek. Search phrase used was:

"2017 HP 24-g080na no sound from ALC256 on Ubuntu 24.04"

" For the 2017 HP 24-g080na with an ALC256 audio codec on Ubuntu 24.04 , the most effective fix involves using hdajackretask to unmap the stuck headphone jack pin.

  1. Install the tool :
sudo apt update
sudo apt install alsa-tools-gui
  1. Retask the pin :
  • Run hdajackretask in the terminal.
  • Select Realtek ALC256 from the dropdown.
  • Check Show unconnected pins .
  • Locate the Headphone Jack pin (often marked as "Always connected" or "Plugged").
  • Change its setting to Not connected (or adjust to the correct type if it is misidentified).
  • Click Apply now and then Install boot override .
  • Reboot the system.

If this does not resolve the issue, try blacklisting the conflicting driver by adding blacklist snd_soc_avs to /etc/modprobe.d/alsa-base.conf and running sudo alsa force-reload , or simply reinstalling PulseAudio with sudo apt install --reinstall pulseaudio .
