mono pin complex are usually [Fixed] Speaker instead of [Jack] Line Out

it is ignored by the auto parser because [N/A] instead of [Fixed]

do widge 0x3e has amp-out for subwoofer volume control ?

as the mic jack cannot be retasked as output , No need to put hp in lineout

multiout.extra_out seem support multi stereo streams in
snd_hda_multi_out_analog_prepare()

for (i = 0; i < ARRAY_SIZE(mout->extra_out_nid); i++)
                 if (!mout->no_share_stream && mout->extra_out_nid[i])
                         snd_hda_codec_setup_stream(codec,
                                                    mout->extra_out_nid[i],
                                                    stream_tag, 0, format);

how to put those internal speakers into multiout->extra_out in
via_auto_create_speaker_ctls() when the auto parser put the speaker into
autocfg->lineout ?

only two volume controls at 0x08 and 0x09,
there are three pin complexes 0x24, 0x25 and 0x33
