Internal Mic Not Working on Redmi Book 15 Pro with Ubuntu 24.04

RedmiBook 15 Pro 2023: Internal Mic Not Working After Installing Ubuntu 24.04

The RedmiBook 15 Pro 2023 is a powerful laptop that comes with a range of features, making it a popular choice for many users. However, after installing Ubuntu 24.04, some users have reported issues with the internal microphone, which may not be detected or may not work correctly.

Checking the Internal Microphone

Before attempting to troubleshoot the issue, it's important to confirm that the internal microphone is the source of the problem. To do this, you can check the sound settings in Ubuntu by clicking on the speaker icon in the top right corner of the screen and selecting "Sound Settings." From here, you can check the input device and ensure that it is set to the internal microphone.

Checking the Kernel

One possible cause of the issue is an outdated kernel. Ubuntu 24.04 comes with kernel version 5.13, which may not include the necessary drivers for the RedmiBook 15 Pro 2023's internal microphone. To check the kernel version, open a terminal and enter the following command:

If the kernel version is 5.13 or lower, you can try updating to a newer version. To do this, enter the following commands in the terminal:

Once the installation is complete, restart your computer and check the sound settings again.

Checking the Sound Card

Another possible cause of the issue is a problem with the sound card. To check the sound card, enter the following command in the terminal:

This will list the available sound cards on your system. Check to see if the internal microphone is listed. If it is not, there may be an issue with the sound card or its drivers.

Checking the Microphone Settings

If the internal microphone is detected but not working, you can try checking the microphone settings. To do this, open the "Sound Settings" window and select the "Input" tab. From here, you can adjust the microphone level and test the microphone.

Reinstalling Ubuntu

If none of the above solutions work, you may need to reinstall Ubuntu. Before doing so, make sure to back up any important data. To reinstall Ubuntu, boot from the installation media and follow the on-screen instructions. During the installation process, make sure to select the option to install third-party software, which will include the necessary drivers for the internal microphone.

• Confirm that the internal microphone is the source of the problem.
• Check the kernel version and update if necessary.
• Check the sound card and its drivers.
• Check the microphone settings.
• Reinstall Ubuntu if necessary.
