No audio through speakers but headphones work fine

Question

This is my first question on this site.

Anyways i'm making a program that will prompt the user for how many grades to enter. Then prompt the user to enter grades between 0 and 100 and store them in a array. Finally traverse the array to find the highest grade entered and display it to the user.

The problem i'm encountering is i have no clue on how to traverse through an array to compare two indexs in a array.

import java.util.*;

public class HighestGrade {

    public static void main(String[] args) {
        //Declare and Initialize Arrays and Scanner
        Scanner scan = new Scanner(System.in);

        int num = 0;
        int[] array1;
        int highestgrade = 0;


        //Prompt user on how many grades they want to enter
        System.out.print("How many grades do you want to enter: ");
        num = scan.nextInt();
        array1 = new int[num];

        for(int i = 0; i < array1.length; i++){
            System.out.print("Enter grade out of 100: ");
            array1[i] = scan.nextInt();
        }

        //Traverse the array to find the highest grade entered

        for (int i = 0; array1[0] < array1[i]; i++){
            System.out.print("Higher");
        }

        //Display the results to the user
        System.out.print("The highest grade is " + highestgrade + ".");

        //Close scanner
        scan.close();

    }
}

Solution

After launching alsamixer in a terminal:

• left/right arrows key to move around faders,
• up/down arrows to increase volume (speaker in your case)
• "m" key to mute/unmute
• Press F6 to select another soundcard (modern pc often have one more soundcard for HDMI output, sometimes the main soundcard if the second one)

If you have no luck, try to run and share Alsa-info script as explained here:

You should read about arrays. docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.htm‌​l
