Hvordan skal du spille av musikk, litt usikker på hva du mener.

Ellers kan du strekke en ledning fra der den skal inn, og lage anlegget inni helt vanlig, da slipper du iallefall mye surr. (Spess om du ikke vet helt hva du driver med.)


Legge ut video? Kult og sett hvordan det blir.

Tro meg, du har ikke lyst til å bruke den høyttaleren...

Men for all del... Dra den ut av lydkortet, og koble den til lydutgangen. (Enten ved å la den gå ut av pcn og så inn igjen, eller lodd den på hvis du er skikkelig tøff )

Det heter PC-speaker.

Jeg hadde engang et hovedkort med integrert lydkort som hadde en innstilling i BIOS for å kjøre lydavspillingen til PC-speaker.
Eller mulig det var motsatt, at PC-Speaker-lyder kom ut "Line Out" på lydkortet.
Er nok ikke støttet overalt, men du kan jo forske litt rundt i BIOSen din

The PC speaker is normally meant to reproduce a square wave via only 2 levels of output, driven by channel 2 of the Intel 8253 (PC, XT) or 8254 (AT and later) Programmable Interval Timer operating in mode three (square wave signal). The speaker hardware itself is directly accessible via PC I/O port 61H (61 hexadecimal) via bit 1 and can be physically manipulated for 2 levels of output (i.e. 1-bit sound). However, by carefully timing a short pulse (i.e. going from one output level to the other and then back to the first), it is possible to drive the speaker to various output levels *in between* the two defined levels. This effectively allows the speaker to function as a crude DAC, thereby enabling approximate playback of PCM audio. This technique is called Pulse-width modulation (PWM) and is notably used in class D audio amplifiers.

Getting a high fidelity sound output out of this technique requires the switching frequency between the minimum and maximum sound levels to be much higher than the audio frequencies meant to be reproduced (typically with a ratio of 10:1 or more), and the output voltage to be bipolar in order to make better use the output devices' dynamic range and power (e.g. by making a loudspeaker vibrate in both directions). On the PC speaker, however, most of these conditions don't hold; for example, the physical properties of the speaker lacks the response time for such high rates, and the output voltage is either zero or TTL level (unipolar). As a result, the precision of this technique when used on the PC speaker is comparable at best to a 6 bit PCM DAC, while the final audio results will depend on precise timing and the nature of the reproduced sound.

The audio fidelity of this technique will be further decreased by the lack of a properly sized dynamic loudspeaker, typical of modern machines and particularly laptops, that use a piezoelectric speaker. The reason for this is that PWM-produced audio requires a low-pass filter before the final output in order to suppress switching noise and high harmonics, something which a normal dynamic loudspeaker can do on its own right, while a piezoelectric speaker will let most switching noise pass, as will many direct couplings (though there are exceptions to this, e.g. filtered "speaker in" ports on some motherboards and sound cards.)

Nettopp. Skal du absolutt bruke den, må du fjerne kontakten, for så å gå til angrep på ledningene med loddebolt.

jeg sitter med en maskin som gjør det der orginalt!
det heter LAPTOP!
hvorfor ikke gjøre det enkelt? ;D
