• Manufacturer Part Number: alc658
• Description: Six-channel Ac?97 2.3 Audio Codec
• Manufacturer: Realtek Semiconductor Corporation

6.1.21. MX32 PCM Input (1
Default: BB80H
The ALC658 supports the following sampling rates, as required in the PC99/PC2001 design guide.
Note: If the value written is not supported, the closest value is returned.
When MX2A.0=0 (VRA is disabled), this register will return BB80h when read.
6.1.22. MX34 PCM Input (2
Default: BB80H
The ALC658 supports the following sampling rates, as required in the PC99/PC2001 design guide.
Note: If the value written is not supported, the closest value is returned.
When MX2A.0=0 (VRA is disabled), this register will return BB80h when read.
