Make sure your speaker is connected correctly to the logic board. If it is not, then connect it properly and see if it works. If the speaker is connected and no sound is produced, then the problem lies in either the speaker being broken or the logic board not picking up the speaker as a device. First try replacing the speaker. If this fails, replace the logic board. [[HP 7 1800 Troubleshooting|See troubleshooting for more info]].
