And finally, the mainboard makes use of Realtek’s ALC880 AC’97 codec. It reproduces sound in the High-Definition Audio format, automatically detects devices attached to the audio connectors, and supports SPDIF connectors (the mainboard offers a coaxial output) and so on.
The parameters of this codec can be set up in the mainboard’s BIOS like shown below:
The results of my checking the audio section with RightMark AudioAnalyzer 5.5 are presented below:
Frequency response (from 40 Hz to 15 kHz), dB:
Noise level, dB (A):
Dynamic range, dB (A):
IMD + Noise, %:
Stereo crosstalk, dB:
IMD at 10 kHz, %:
General performance: Good.
So, the voice of this mainboard sounds quite good.
