| Subject: ALSA: hda/realtek - Avoid bogus HP-pin assignment |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| commit 5fe6e0151dbd969f5fbcd94d05c968b76d76952b upstream. |
| |
| When the headphone pin is assigned as primary output to line_out_pins[], |
| the automatic HP-pin assignment by ASSID must be suppressed. Otherwise |
| a wrong pin might be assigned to the headphone and breaks the auto-mute. |
