Dear Mark, Liam
Is ALSA or someone controlling that sound card is working ?
I'm afraid below case.
ex) FSI-AK4642
# insmod snd-soc-ak4642.ko
# insmod snd-soc-fsi-ak4642.ko
#
# aplay sound.wav
# rmmod snd-soc-fsi-ak4642.ko
I guess noone call soc_pcm_trigger(xx, STOP);
who should control it ?
Best regards

I wouldn't 100% rely on that being the case - if the driver is forcibly
removing itself from underneath the subsystem then it's not clear if
this is a useful thing to try to do. I'd expect that this is something
the ALSA core should do if required.
