Question about conversion kcontrol to component
by Kuninori Morimoto 24 Apr '25

24 Apr '25

Hi ALSA ML I have noticed that we have similar functions snd_soc_kcontrol_component() snd_soc_dapm_kcontrol_component() Both converts snd_kcontrol to snd_soc_component. I wonder can we merge these ? or which we can use is case-by-case ? Thank you for your help !! Best regards --- Kuninori Morimoto

Pioneer DJ DJM mixers channel names
by František Kučera 24 Apr '25

24 Apr '25

When working on DJM-V10, I noticed that other Pioneer mixers (like my older DJM-250MK2) have control names that do not comply with conventions described at <https://docs.kernel.org/sound/designs/control-names.html> and thus do not show in alsamixer under proper category (playback/capture) and they are all under playback. I am preparing a patch that will add "Playback Switch" or "Capture Switch" suffix to control names. But I am not sure about the prefix. Should it be "aux" or "PCM"? It is often the main function, so I tend rather to PCM than auxiliary... Could you give some advice regarding the mixer control names? Thanks, Franta
