One. The maintenance move that sound blocks
If acoustical card cannot make sound box sounds, have the following kinds of common causes:
1. Sound box was not opened open it please.
2. Sound box electrical outlet asks accurate installation to be on Speaker electrical outlet without correct installation.
3. Sound blocks driver to lose reinstall sound to block driver please. (the driver that sound blocks is very easy missing) .
4. Sound gets stuck and other the each setting value that board card sets card correctly please afoul.
5. Sound blocks trouble removal above each hind itself of only phonic card has trouble, change please new sound gets stuck.
2. AC'97 technology introduces
Introduction ENET about AC'97 technology is below
Chinese consumer is having special consumptive idea- - pay attention to only main, and neglect is minor. When buying computer, this one idea particularly apparent, often say turkey to one and bazzard to another. In CPU, advocate board, show a large amount of fittings such as card to go up, the choose and buy is absolutely explicit. And go up in the gadgety choose and buy such as acoustical card, it is to be like two different people however, can feel 2, 100 yuan of 3 card that buy reputation calculate very fervent. Most not beautiful Qian Maisheng gets stuck- - advocate board on compositive AC'97 weak tone gets stuck. Nevertheless, ace of a few so called computer is right however so a gratuitious sound blocks a requirement quite tall, of dagger of dagger of shellfish of deficient of one's previous experience it is condemned accordingly repeatedly.
1. Does weak tone of He Wei AC'97 get stuck?
People often regards the pronoun of card as AC'97, actually this is an error on understanding completely. Come this year, multimedia technology on personal computer popularize increasingly, gain ground and apply. Provide the phonic effect framework of high quality, low cost to can be on PC. In June 1996, the Intel of 5 PC manufacturer that heads with Intel, Creative Labs, NS, Analog Device and Yamaha put forward Audio Codec'97 jointly (abbreviation AC'97, meaning make up ／ decoder " for signal of number of multimedia of " sound effect) standards standard. The biggest innovation is structure of " of " double chip, make ADC (Analog - To - Digital Conversion, imitate revolution word) with DAC (Digital - To - Analog Conversion, the number turns imitate) changeover severs a system as far as possible, can avoid major figure so / the clutter that when imitate signal is changed, produces, get better phonic effect quality thereby. At present all acoustical card supported AC'97. Not be pure ground is referred in particular to advocate board on compositive weak tone gets stuck. And card of AC'97 weak tone is another concept. It just is based on the CODEC chip of AC'97 one piece, do not contain digital frequency to handle unit, when because this computer is in,broadcasting frequency message, besides D/A and A/D changeover all processing jobs should give CPU will finish. Such OK saying, card of AC'97 weak tone just simplified hardware, and the sound that design train of thought still is the standards standard that implements AC'97 gets stuck. The AD188x that card of current AC'97 weak tone has Analog Devices (AD1881, AD1885, AD1886) , ALC201/A, VIA VT1611A.
