B10.5.4.2.5 Supports digital audio detection and digital audio quality on CD-ROM drive
CD and DVD drives must implement "CD Capabilities and Mechanical Status Page" (2Ah), as defined in the MMC-2 standard. The bit "CD-DA Commands Supported" must be set and the functionality must be implemented.
CD and DVD drives must also implement and set the bit "CD-DA Stream is Accurate" of "CD Capabilities and Mechanical Status Page." The READ_CD command and READ_RAW commands must provide sector-accurate reads, as defined in MMC-2. Data alignment accuracy must be equivalent to that of data reads. Because of the lack of error correction code (ECC) bytes used for data tracks, the data itself may contain inaccuracies due to physical defects of the media.
A CD-R/RW drive must support the following commands, as defined in SFF-8090 and MMC-2:
