Public bug reported:
[Impact]
No audio output from the built-in speaker and the speaker and mic mute LEDs
never turn on on affected HP systems (SSIDs 0x103c:0x8f94 and 0x103c:0x8f95).
================ Linux Kernel ========================
[Fix]
Add the ALC245_FIXUP_HP_TAS2781_I2C_MUTE_LED quirk to enable speaker and mic
mute LEDs for SSIDs 0x103c:0x8f94 and 0x103c:0x8f95.
================ linux-firmware ========================
[Fix]
Backport upstream fix a16ce5c67 ("linux-firmware: Add firmware for new
projects")
[Test Plan]
1. Boot up the affected machine
2. Check the audio output by pressing `Test speakers` on the g-d-d sound menu.
3. Press the speaker and mic mute keys and verify the following
- Speaker muted: LED is on
- Speaker not muted: LED is off
- Mic muted: LED is on
- Mic not muted: LED is off
[Where problems could occur]
This change is restricted on particular SSIDs. Should be no risk of regression.
