Thank you for your valuable feedback. Since this is my first course, I apologize for not paying close attention to the volume control. As you mentioned, I will better balance the lecture audio and notification (Line) sound volumes, so that you can listen more comfortably in the next course and future updates. Thanks to your feedback, I believe I can improve the course in a better direction. Thank you once again for taking the course and leaving your comments. 🙇‍♂️
