| Subject: ALSA: hda - add mute LED for HP Pavilion 17 (Realtek codec) |
| |
| From: David Henningsson <david.henningsson@canonical.com> |
| |
| commit 6d3cd5d444223c41eabb70dccff14fae4e8cb8b1 upstream. |
| |
| The mute LED is in this case connected to the Mic1 VREF. |
| |
| The machine also exposes the following string in BIOS: |
| "HP_Mute_LED_0_A", so if more machines are coming, it probably |
| makes sense to try to do something more generic, like for the |
| IDT codec. |
