Mainboard speaker signal
The computer POST power-on self-test checks a computer's internal hardware for compatibility and connection before starting the remainder of the boot process. If the computer passes the POST, the computer may give a single beep some computers may beep twice as it starts and continues to boot. However, if the computer fails the POST, the computer may generate a beep code telling the user the source of the problem. If your computer has an irregular POST or a beep code not mentioned below, follow the POST troubleshooting steps to determine the failing hardware component. Determine the BIOS manufacturer for your computer's motherboard, then select the appropriate link below for beep code meanings. However, because of the wide variety of different computer manufacturers with this BIOS, the beep codes for your computer may differ slightly from those listed below.

How On-Board Audio Works
The problem TV has no sound can be found on TVs of all brands. Unfortunately, discovering that your television set emits no sound is a rather common problem. The various possible reasons for TV sound problems and you can find some quick and easy solutions below. This might seem like a minor cause of TV sound problems, but it is an important aspect to keep a firm eye on before panicking. Many people forget to turn their TV volume up or sometimes even leave it muted.
The first and most important thing to do when a TV sound problem occurs is to check the volume level and ensure that it is turned on as well as unmuted. Unsecured television cables could also lead to the absence of any sound from your TV. Someone might have accidentally pulled off a plug cable from the external speaker device, restricting all sound output from your TV.
You can get a new cable if any of the TV set cables are damaged. So when your TV produces no sound, you should check to ensure that the cables are secured and that none of them is cut, removed, disconnected or loose. This is another potential cause of TV sound problems. The source of the TV signal should be strong and must be more than 20db. Perform a signal check on the TV; that might be the solution to your TV sound issue. The mainboard, which may also be referred to as the motherboard, is more or less like the spine of the TV set.
This would surely help to restore the TV sound. This is another possible reason why a TV may not be producing any sound. The software version or the driver might be out-dated, and this can affect some or all channels.
If your television has the analogue broadcast feature, you should consider performing an analogue broadcast tuning to see if there is any noise. If there is any noise at all, and there are sounds coming from the television, you might need to just check other causes like playback content or connected appliances for sound. To correct the sound issue, you might need to replace or adjust the source device. Sometimes, temporarily unplugging the connected cables might help resolve your TV no sound issue.
This temporary reset works to clear the short-term memory of the television, and also helps to resolve some other issues. Also, ensure that no wired or wireless headset is connected to the Television Set and that the input selection is correct.
For example, if Aux being selected, it may prohibit the TV from producing sounds. Though all your personal settings will be removed, it is practically guaranteed that the sound will be restored if you reset your television set to its factory setting.
You can do this by holding down the menu button for about 10 seconds; follow the on-screen instructions to complete your restore factory settings.

I want to be able to switch audio outputs on the fly. Is this possible? When I unplug my headphones, my external speakers work with an audio output of 'Line Out'. Then I plug my headphones back in the front and music plays through them, with the audio output now back to 'Headphones' and the 'Line Out' audio output disappears. If I were you I would install alsamixer. It allows you to change the volume on different devices.

The second one can neither be controlled in its volume nor be heard out of the normal speakers. But one can change this. For doing this one needs a sound card with an unused input Line-In or, available on most original SoundBlaster-Cards, a special input for it. The only thing to do is making the cable for it, the sound card itself remains unchanged. The mainboard speaker connector consists of 4 pins, however only the outer 2 are used.

Connect and share knowledge within a single location that is structured and easy to search. Most 12v relays I've come across require 4v to switch on. Using C or any programming language I can send a frequency and duration signal through the motherboard speaker pins so I'd like to use this as a cheap mod to control an actuator. A motherboard buzzer takes a lot less current to operate than a relay winding.
