This is easy. The problem is that I am already using model "no-jd",
remember?
In this case, if I used

        /* was 0x01113014 */
        if (spec->board_config > STAC_92HD73XX_NO_JD ) {
            stac92xx_set_config_reg(codec, 0x0c, 0x01813021);
        }

would be fine to me.

However, there is a possibility that all "stac92hd73xx" family needs
this quirk. In this case, no additional code is needed.
