Sorry for not replying earlier. Mainly cset "name='MIXINR PGA Volume' 0,0" made things much better indeed. I took a break from this then and the issue is still open, here: https://source.puri.sm/Librem5/librem5-base/-/merge_requests/296 or if you want to look at the current ucm file: https://source.puri.sm/Librem5/librem5-base/-/blob/bb48912242dd0db1f35c6de8425984414c6d37bb/default/audio/ucm2/Librem_5/HiFi.conf As you know I'm no expert with the codec and this definitely can be improved: When visualizing the signal, it doesn't look "good" yet and the signal strength seems to only go to 50% of the available scale (in the gnome volume setting). Actually I'll talk about this to Guido tomorrow and even though it is kind of usable now, I hope to that we can come up with a profile that we're preliminarliy happy with. Of course we already use your "Input Mode" control. thanks, martin
