How to fix laptop sound issue in ubuntu OS

Fixing Sound Issue on Ubuntu Laptop

If you're experiencing sound issues on your Ubuntu laptop, you can try adjusting the default sample rate in the PulseAudio configuration file using the Vim text editor. Here's how:

1. Open a terminal window. You can typically do this by searching for "Terminal" in the applications menu or by using the keyboard shortcut Ctrl + Alt + T.
2. Run the following command in the terminal:
sudo vim /etc/pulse/daemon.conf
3. This command will prompt you to enter your password because it requires superuser privileges to edit system-wide PulseAudio configuration.
4. Once the file is opened in the Vim text editor, navigate to line number 82 by typing :82 and pressing Enter.
5. Modify the line default-sample-rate to set it to 48000. If the line doesn't exist, you can add it. The modified line should look like this:
default-sample-rate = 48000
6. After making the changes, press Esc to exit the insert mode if you're in it, then type :wq and press Enter. This will save the changes and exit Vim.
7. Restart the PulseAudio service to apply the changes by running the following command:
sudo systemctl restart pulseaudio

After following these steps, the default sample rate for PulseAudio should be set to 48000, which may help resolve any sound issues you're experiencing on your Ubuntu laptop.
