The volume of my built-in speaker is not loud enough

There is a volume button on the phone to increase(up arrow) and to decrease(down arrow). Keep pressing the up arrow to increase the volume till you can hear clearly either with speaker or without speaker.

Laptop built in speakers come with a very limited volume. Though it shows 100% the sound is not enough. That is because they are not amplifiers they are simple speakers.

If you want to get more sound, you can connect a big speaker (amp) via an auxiliary cable. And give the power supply for the amp seperately.

There are a few sotfware which will increase your sound but it is not good for the speakers as they are not designed for very loud noises like that.

The computer sound card has to have enough umph to drive the speakers. Most Netbooks and some laptops just don't have enough power to create loud sound.

Buy yourself some stand alone speakers, a base & two side speakers, they cheap these days, base speaker has buit in amplifier & plugs into mains, or get surround sound 5speakers & a base, again mains powered, loud enough to annoy neighbours on full. Built in monitor speakers are renowned feeble tinny sounds. Right click speaker icon, bottom right, on your desktop toolbar, open volume control, ensure volume sliders set to max.

We have 3 ENV2's in our family. None of them have volume problem. The speaker phone is especially loud when used in indoor environment. It is so loud that I have to turn the volume way down when used with good quality ear set. You probably are right about the phone being defective.

There are 2 volume control buttons on the laptop. 1 turns it up 1 turns it down. Try turning the volume up. It may be up high enough for you to hear with headphones but now loud enough to be heard through the speakers.

The built in speaker is not so loud in this phone. But if the speaker is comparatively low than other same model phones, then you need to change the speaker on back side.

Connect the projector to an external amplifier and speakers.
The speaker system built in is designed for watching movies etc in a small quiet room.

Hope that helps =)

Try other speakers with the card.
Most speakers have an amplifier built-in them. Most of the time they go slowly, which may be the case.

The built-in speaker amp or the volume switch may be going bad on you. A quick test is to disconnect the speaker set and replace it with a headphone or another working speaker set. If it behaves normally then the problem is in your original speakers, if not then you may have software driver issues or less likely an issue with the sound card. Let us know what you find out.
