I've installed three applications such as "Free Dictionary", "Audio Book", "Advanced Dictionary" and they work well except the sound.
When I click on the sound for starting the pronunciation or starting the audio book, I cannot hear any sound. These applications work well on my brother's laptop which is also Windows 8, but on my laptop they don't.
Please note that my sound driver is working on my HP laptop, because if I try to play any music or watch DVD, I can hear them.
How can I begin to troubleshoot this?
