Moinz Leude,

HAbe vor mir das EPOX Board zu holen.

Hat schon jemand ERfahrung mit dem onboard Sound gemacht?

6 Kanalsound onboard! Ruled das?

das hat noch den ac 97er codec und ich hab mich mal umgesehen

AC97: a good idea suffering from bad implementation?

While the PCI bus had the necessary bandwidth for handling multiple wave channels, sound cards continued to have considerably higher costs. After the development of higher clocked processors, Intel introduced the AC97 standard in 1996. The AC97 CODEC was the first move in developing lower cost sound solutions with more than adequate sound quality. Since the most expensive parts of a sound card are the DSP (Digital Signal Processor) and the ADC/DACs (Analog to Digital Converter/Digital to Analog Converter), elimination of either was necessary in order to build a cost-effective solution. In the end, it was the DSP to be axed as its various functions could be processed by the host CPU through specially written drivers.

Since then, most motherboard chipsets have AC97 support which can be paired with a AC97 CODEC (COder/DECoder). The AC97 CODEC features at least a 2-channel ADC (Analog to Digital Converter), a 2-channel DAC (Digital to Analog Converter), a mixer and a I/O controller. The basic idea behind AC97 integration is exactly the same as with software modems where part of the workload of the modem is done by the host processor. All modern PCI sound cards have AC97 CODECs and a DSP while most motherboards with integrated audio make use of only the AC97 standard.

While the introduction of the AC97 standard was the right move for the industry (decent sound reproduction at low cost), there are a few problems. First of all, since the AC97 is considered to be a low cost alternative, many motherboard manufacturers provide AC97-ready motherboards with poor sound quality. This was the result of bad design, improper shielding and a lack of effort to provide a decent sound solution.

Though our words may seem harsh, the cold reality is that in practice, very few boards even offer sound quality comparable to lower cost sound cards. In addition, most AC97 manufacturers have been providing solutions with limited features (lack of bass/treble adjustments, lack of S/PDIF In/Out, no support for DirectSound3D APIs, etc.).

Der sound ist wahrscheinlich nicht schlecht aber onboardsound ist immer noch qualitativ nicht so hoch, wie bei ner richtigen soundkarte, aber wenn deine ansprüche nicht so hoch sind kannste wohl damit leben. wie in dem artikel beschrieben liegt das am mainboardhersteller, wie die sound qualität ist, kann dir das aber jetzt nicht sagen ob der sound ruled, weil ich das board nicht habe.

hoffe habe dir trotzdem etwas geholfen.
