Public bug reported:
On Ubuntu 24.04 with kernel 6.14, internal speakers do not produce sound
on Lenovo Legion 7 16IAX10.
Hardware uses:
- Realtek ALC287 codec
- Dual Cirrus Logic CS35L56 smart amplifiers
Driver loads correctly, but dmesg shows missing firmware:
cs35l56-hda: .bin file required but not found
Relevant dmesg excerpt:
cs35l56-hda i2c-CSC3556:00-cs35l56-hda.0: .bin file required but not found
cs35l56-hda i2c-CSC3556:00-cs35l56-hda.1: .bin file required but not found
DSP system name reported by driver:
'17AA392C-spkid1'
SOF is enabled, no kernel audio overrides are in use.
HDMI audio works as expected.
Bluetooth/USB audio works as expected.
This appears to be missing Cirrus CS35L56 firmware/calibration data in
linux-firmware for Lenovo SSID 17AA392C.
