[Sound-open-firmware] jack detection via input/event on linux

3 Jun 2022


      Hi all,
I don't know where to ask this question so please point me to the right 
direction if I'm wrong here and if you know a better place to ask this 
questions. I tried to ask it on the alsa-user list but there was not a 
single response - not even a negative one.
I'm using a chromebook Lenovo IdeaPad i3 with Debian 11. Intel Jasper 
Lake platform, alsa modules snd_soc_rt5682, snd_soc_rt1015, etc.
The sound generally works, except I have to manually set mixer settings 
to have sound and it's making click-noises with every new stream and the 
headphone jack detection doesn't work. And the internal microphone has 4 
channels with gray noise on channels 3+4, because there are onle two 
channels connected in this device (there are two mono microphones / one 
stereo... don't know).
The kernel is Linux 5.10 from the ChromeOS/chromiumOS project, the SOF 
firmware is sof-v2.1.1 (sof-jsl.*) from thesofproject, the alsa ucm is 
copied from the device filesystem (ChromeOS).
For jack detection there is some input event device /dev/input/event9 
"sof-rt5682 Headset Jack" which works. I can see input events via evtest 
if I insert or remove the headset.
This device belongs to:
cat 
/sys/devices/pci0000:00/0000:00:1f.3/jsl_rt5682_rt1015/driver/jsl_rt5682_rt1015/modalias
platform:jsl_rt5682_rt1015
I don't know if there should be some "device-internal" 
jack-detection-service for this besides the input event device the 
kernel offers to userland and how headphone jack detection works in 
general for alsa/pulseaudio. The documentation neither for SOF nor alsa 
nor pulseaudio was eye-opening for me, sorry :-(
Everything I tried to modify the alsa ucm failed so far.
For ChromeOS it seems the ChromeOS sound server "CRAS" is responsible 
for headphone jack detection. The alsa ucm seems to have special 
functionality for CRAS? (see below for the Hifi.conf)
And the functionality which is offered by the SOF firmware+driver is not 
compatible with alsa/pulseaudio?
Or does anybody know how to tell alsa or pulseaudio or maybe pipewire to 
listen to the input event device to enable headset output and switch to 
the headset device?
