These patches are based on Linus's tree after merging the sound updates and I just verified that they apply cleanly to 6.8-rc1. I couldn't find anything related in either linux-next or your ASoC tree that should interfere. Could you please try again or let me know which branch to rebase on? Johan

I was applying it against v6.8-rc1.

That's what I assumed, but I still don't understand why it doesn't apply on your end: $ git checkout -b tmp v6.8-rc1 $ b4 am 20240119112420.7446-1-johan+linaro@kernel.org ... $ git am ./v4_20240119_johan_linaro_asoc_qcom_volume_fixes_and_codec_cleanups.mbx Applying: ASoC: codecs: wsa883x: fix PA volume control Applying: ASoC: qcom: sc8280xp: limit speaker volumes Applying: ASoC: codecs: lpass-wsa-macro: fix compander volume hack Applying: ASoC: codecs: wcd9335: drop unused gain hack remnant And if I generate patches from this branch, the diffs are identical to the v4 patches I sent. Could you please try again, and tell me which patch fails to apply and how it fails? Johan

Ok, thanks. No idea what goes wrong here. I just sent the regenerated patches as a v5. Johan

The UCM configuration for the Lenovo ThinkPad X13s has up until now been setting the speaker PA volume to the minimum -3 dB when enabling the speakers, but this does not prevent the user from increasing the volume further. Limit the digital gain and PA volumes to a combined -3 dB in the machine driver to reduce the risk of speaker damage until we have active speaker protection in place (or higher safe levels have been established). Note that the PA volume limit cannot be set lower than 0 dB or PulseAudio gets confused when the first 16 levels all map to -3 dB. Also note that this will probably need to be generalised using machine-specific limits, but a common limit should do for now.
