Please post the output of alsa-info.sh

Do your VIA 8237/ens1371 has any digital output/input ?

Why do PA server try to open an non-existing device iec958 so many times ?

Have the PA developer ever tested those profiles on their machines "
recording on Digital Surround 4.0 (IEC958) (iec958-surround-40)" ?

Did PA server check any error when open those device ?

it is quite strange that PA still call snd_pcm_hw_params() when there is
error "Cannot lock ctl elem" ?
