  • Patch Set #2, Line 45:

    /*
    	 * The verbs above are for a HD Audio front panel.
    	 * With vendor firmware, if audio front panel type is set as AC97, line out 2
    	 * (0x1b) and mic 2 (0x19) pins of ALC887 are configured differently.
    	 *
    	 * The differences are all in the "Misc" fields of configuration defaults (in byte 2)
    	 * as shown below. ALC887 datasheet did not offer details on what those bits
    	 * (listed as reserved in HDA spec) are, so we'll have to take their word for it.
    	 *
    	 * Pin  | 0x19 | 0x1b
    	 * -----+------+-----
    	 * HDA  | 1100 | 1100
    	 * AC97 | 1001 | 0001
    	 */
    

    I tried to see if there was anything in the Linux kernel that revealed what those reserved bits were being used for but couldn't find anything.
