Speakers dont sound

this is something a tech expert on electronics can handle. even replacing parts has to be attended by a pro-technician. something is wrong with your DSP processor or system components. it could be the switch only or it could be the processor.

Yes you need to hook it up to an amplifier and speakers through RCA cable on the back. And or you can use headphones if there is a headphone jack?
Also make sure there is something recorded on the reel tape in the first place. You can do a test recording of something like a CD from your CD player or record something, then play it back, make sure you turn the record input volume knob up and make the RCA connections on the back of the reel unit and connect to your playback source you want to record. When you playback the reel tape, the db meters should be moving on the front of the reel deck, if they move then you most likely have some sound recorded on the reel tape.
If you still can't hear any sound and the db meters are moving, then check all your connections again and volume output knob on the reel deck. Hope this helps?

check all the power transistor and resistor in the amplifier section, check also the power supply for correct voltage. if all the components are good next step is check the speaker. leaky capacitor makes your amplifier a popping sound output. i hope this may help you... good luck...

Sometimes the headphone jack has its own volume control separate from the internal speakers. Check the levels in the volume mixer.

SOURCE: No sound at laptop speaker but audio output is ok

I have lenovo notepad 3000n100 with winXP sp2.
I downloaded realtek audio from ibm site and installed.
Now sound is coming at my output port but the in-built laptop speaker is not giving any sound output.
The hardware is ok as the sound was coming at in-built speaker before formatting. The previous audio driver set up file i have lost.
