** Description changed: + [SRU Justifications] + + ========== linux-firmware ========== + [Impact] + + Audio output doesn't work on Dell Bolan platforms with CS35L56 speaker + amplifiers + + [Fix] This requires following firmware blobs: - * linux-firmware - - https://github.com/CirrusLogic/linux-firmware/commit/367fda8e56d7dda4c138438493e2bf6b9b92ce7b - * firmware-sof - - sof-lnl-cs42l43-l0.tplg, not yet released. + - https://github.com/CirrusLogic/linux-firmware/commit/367fda8e56d7dda4c138438493e2bf6b9b92ce7b which is not landed in linux-firmware mainline yet. + + [Test Case] + 1. Boot up the machine of Dell Bolan platform with CS35L56 speakers + 2. Verify the sof-lnl-cs42l43-l0.tplg in in the /lib/firmware/intel/sof-ipc4-tplg/ + 3. Verify with checking the output of `aplay -l` command with valid sof output device. Should never be dummy output. + + ========== firmware-sof ========== + + [Fix] + This requires following tplg file in firmware-sof + - sof-lnl-cs42l43-l0.tplg + upstream firmware-sof 2.10 will have this tplg file included. + + [Test Case] + 1. Boot up the machine of Dell Bolan platform with CS35L56 speakers + 2. Verify with the linux-firmware with new CS35L56 amplifier support. + 3. Verify with checking the output of `aplay -l` command with valid sof output device. Should never be dummy output. + + + [Where problems could occur] + It only affects the Dell Bolan platforms with the new CS35L56 amplifier. Should be low low risk of regression
