Very low audio

Problem could be in either the record or playback circuits of unit. Try playing back a tape in another machine to see what the volume is like. If also low then the issue is with the record amp circuits.
Fixing will not be cost effective, however.

Try connecting them to another amplifier...you can use the speaker output of a guitar amp as a quick test. If the amp (and mixer) check OK, it sounds like you are about to become good friends with your local speaker reconing shop.

Remember...Distorted Audio Can Kill Speakers even at low volumes. It happens because sine waves become square waves. Google it for additional information.

Have you connected the speakers correctly. When you connect the cord to the ports on the back do you get a popup asking what has been connected and there are options for headphones,line-out etc. Can you see a speaker icon in the status bar? The area with the time on it. Double clicking will bring up the audio properties. Check the volume levels for all like wave,sw-synth etc an check if none of them are muted and even check the main volume , last but not least check the volume on the external speaker or headphones , could be that they are set low.
Hope this helps..

Your volume levels and effective impedance becoming too low can lead to a receiver self-protecting. It's trying to tell you something and will eventually die completely if you don't address the cause.

We would need more details regarding models and exact configurations. Keep in mind that an amp driven to distortion is very dangerous to itself and the attached speakers as distortion lacks the smooth sinusoidal transitions that normal audio has. Square waves or briefs burst of DC will take a toll eventually.

Hi,

The audiolevel is much to low for a headphone.
You really need to use a headphoneoutput ( if its there) or a headphoneamplifier.
You tried to connect your headphone on line-level outputs.

Have you selected a different setting in the audio control section of your computer? For example: wave out, instead of line in or vice versa. Is the audio control input set low?

Reinstall the driver

if the problem persists, check hardware

I had the same problem and had to fix with a work around. I take the audio directly from my cable box and pipe it in to an external 'theater in a box' system.

Do you have a universal remote code?

I'm sure you went to Control Panel, opened device manager, and and checkeck for any yellow checks for your
sound, video and game controllers. If there are none, your system is go. Then go to your audio manager on control panel, and set it up for whatever speaker configuration you have. I have realtec audio manager. This step is a must for configuring—you choose whether your laptop will use its own speaks or use your external speakers—you have to turn off the internal speakers and turn on the external. Did you forget?

Loudness Equalization : on

Equalizer: Choose one (Jazz seems to be loudest setting but sounds of hallway effect so I use powerful for clarity.)

This has more than doubled the level of volume on my acer 5570.
