IPAD Sound gone , Headphone works Please suggest

Question

Suddenly my IPAD sound is gone , None of the application is giving any sound , But when i plugin the Headphone it works .
I went to the Apple store and showed the  IPAD and they said the Speaker is blown out . and to fix the issue they will charge 300$
But i am having the hard time to beilive it ,as i was researching on the GOOGLE and found out if you have some dirt or something in the charging hole it may cause the sound to be gone , i tried to clean it and yes it was back for some time it showed the Volume control in the task bar (controler)
but again it went off after i played it for minute and two .. .and after that i cleaned a lot and it never came up .
I tried reseting the IPAD rebooting several time and nothing works ...
seems like i was robbed .. i bought the IPAD for 600$ and now as new ipad is cooming 500$ they are asking me to pay 300$ to repair it .
I feel like its better to avoide expensive apple stuff if there is no gaurantee .

Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) http://support.apple.com/kb/ht1430
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

To solve some sound problems, just follow these simple steps
1. Go to Settings
2. Tap on General
3. Tap on Reset
4. Tap on Reset All Settings
What this effectively does is to reset some of your Settings to factory default. It’s not a complete removal of settings. It removes all of your preferences for Wi-Fi, Bluetooth, Do No Disturb, Notifications, General, Sounds, Brightness & Wallpaper and Privacy. It doesn’t affect your data. All of your email accounts will remain intact, as well as any SMS text or iMessages.
