   4 Subject: ALSA: hda - Enable line-out detection only with speakers
   5 Patch-mainline:
   6 References: bnc#520975
   7
   8 Enable line-out detection for IDT/STAC codecs only when speaker pins
   9 exist.  In some cases, the speaker itself is identified as line-out,
  10 and this confuses the situation.  Only the extra line-outs should do
  11 auto-muting.
