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