| Subject: ALSA: hda - Fix Dock Headphone on Thinkpad X250 seen as a Line Out |
| |
| From: David Henningsson <david.henningsson@canonical.com> |
| |
| commit ec56af67a10a0d82b79027878a81fce08d002d50 upstream. |
| |
| Thinkpad X250, when attached to a dock, has two headphone outs but |
| no line out. Make sure we don't try to turn this into one headphone |
| and one line out (since that disables the headphone amp on the dock). |
