Identifying the Core Issue

The problem arises from the file path you provided to the FFmpegPCMAudio method. When the path is incorrect, your bot will throw the OSError, prohibiting it from accessing the specified audio file.

Solution: Providing the Correct File Path

To resolve the error, you will need to modify the path to your audio file. Here’s how to do it correctly:

Determine the Full Path: Find the full path of your audio file. For instance, if your file is located in C:\wherever\the\file\is, your audio file will be C:\wherever\the\file\is\BravoSix.mp3.

Update the Code: Replace the existing file path for BravoSix.mp3 in your code as follows:

Important Points to Remember

Use Double Backslashes: When specifying the path, make sure to use double backslashes (\) instead of single backslashes, as the latter can be interpreted as escape characters in Python strings.

Verify File Existence: Always check to ensure that your audio file is indeed in the specified directory and that there are no typos in the file name.

Conclusion

By following the steps outlined in this guide, you should now be able to eliminate the OSError: [Errno 9] Bad file descriptor error and successfully play audio in your Discord bot. Remember, always double-check your file paths and ensure your code is precisely written, as small oversights can lead to frustrating errors.

Now, go ahead and bring your Discord bot to life with seamless audio playback! Happy coding!
