Hi,
HP EliteBook 860 G10 no sound in speakers, 3.5 mm jack working.
The PC has a Cirrus Logic chip after the sound card. On Debian I had to load some custom firmware.
cp cs35l41-dsp1-spk-prot-103c8b47.bin cs35l41-dsp1-spk-prot-103c8b47-r0.bin
This amplifier requires specific firmware files (e.g., cs35l41-dsp1-spk-prot-*.wmfw and .bin) to function properly. Reports show common problems like firmware failing to load or errors such as “Cannot Initialize Firmware. Error: -22” when the correct firmware or device-specific ACPI _DSD properties are missing. Fixes often involve:
