Thinkpad L14 got a senary SN6140 codec, speaker, Dmic, headset mic works fine.
Only no sound output from headphone.

add snd-intel-dspcfg.dsp_driver=1 to kernel cmdline the issue is reproduced too.

When not fully plugin headset, it didn't trigger headphone switch, sound output can be enabled in alsamixer.

Disable pipewire or pulseaudio, the issue is the same as before.
