charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Thanks for your work on this - there is currently a regression on the latest kernel versions (7.2 onwards, as well as LTS kernels 6.12 and 6.18). Trying to set the volume in software like wpctl, or pwvucontrol causes the software volume to be pulled down with it - I think it's something to do with "sticky mixers", not completely sure. I worked through troubleshooting it here as I originally thought it was a wireplumber issue: https://gitlab.freedesktop.org/pipewire/wireplumber/-/work_items/1022 This patch should hopefully solve that, and avoid the usage of external kernel modules like https://github.com/vanzaho/audient-evo-py (which you've based your work from) I'm not exactly sure how the process with kernel stuff works, but considering a regression on current mainline as well as LTS branches for this device - is there some chance of fast tracking the merge of these patches? Thanks, Faaris
