31 * TODO:
32 *
33 * Most vendors connect the surr-out of ad1980/ad1985 codecs to the
34 * line-out jack. So far we haven't found which vendors don't
35 * do that. So we assume that all vendors swap the surr-out
36 * and the line-out outputs. So we need swap the two outputs.
37 *
38 * Historically we internally processed the "ad198x-swap-output"
39 * property. If someday some vendors do not swap the outputs, we would
40 * set "ad198x-swap-output = 0" in the driver.conf file, and unload
41 * and reload the driver (or reboot).
42 *
43 * TODO:
44 *
45 * Since we don't have access (at present) to any such systems, we have
46 * not implemented this swapping property.  Once we can test it, we will
47 * add it.  This is noted as CR 6819556.
48 *
49 * The old code did this:
50 *
51 *	if (ddi_prop_get_int(DDI_DEV_T_ANY, statep->dip,
52 *	    DDI_PROP_DONTPASS, "ad198x-swap-output", 1) == 1) {
53 *		statep->swap_out = B_TRUE;
54 *		(void) audioixp_read_ac97(statep, CODEC_AD_REG_MISC, &tmp);
55 *		(void) audioixp_write_ac97(statep,
56 *		    CODEC_AD_REG_MISC,
57 *		    tmp | AD1980_MISC_LOSEL | AD1980_MISC_HPSEL);
