| Subject: ALSA: hda - Don't turn off EAPD for headphone on Lenovo N100 |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| commit 7a3e6107f94344e65c35bfe62de6c096a7b48965 upstream. |
| |
| The only EAPD on AD1986A is on NID 0x1b where usually the speaker. |
| But this doesn't control only the speaker amp but may influence on all |
| outputs, e.g. Lenovo N100 laptop seems to have this issue. |
