Pro Tip: You usually need to install Intel SST first, reset, then Realtek Audio second.

sudo apt install linux-generic-hwe-22.04 # Ubuntu LTS realtek alc3287 driver

If audio still doesn’t work, you may need a custom UCM (Use Case Manager) configuration file – check /usr/share/alsa/ucm2/ for existing configs like "rt5682" or "cml_rt5682".

Do not download a “.exe” driver – Linux uses kernel modules. Look for files named similar to:

If Windows Update keeps reverting your driver to a generic Microsoft one, follow these steps:

1. The "No Audio" or Generic Driver Issue Sometimes, after a Windows Update, your laptop might switch to the "High Definition Audio Device" generic driver. While this provides basic sound, you lose access to the specific tuning and volume capabilities of the ALC3287. Pro Tip: You usually need to install Intel

2. Microphone Sensitivity A frequent complaint regarding this driver is low microphone volume. The ALC3287 often powers laptop microphone arrays. If the proprietary driver isn't installed correctly, the "Smart Audio" features that boost voice volume don't load, leaving you sounding distant on Zoom or Teams calls.

3. Windows 10 vs. Windows 11 Compatibility Many users report difficulty finding the correct driver when downgrading from Windows 11 to Windows 10, or vice versa. The driver is often packaged differently depending on the OS version.

Microsoft now pushes I2S audio drivers via Windows Update (WU), but they are often generic.

  • On Linux:
  • Test with external devices: known-good headphones and USB microphone help isolate whether the issue is codec vs system-level.
  • Final checks: confirm sample rates (44.1/48kHz) and channel mapping in the OS audio settings; run an audio loopback test to verify mic → speaker path.
