Hey everyone,
I'm currently having an issue with cs4271. The codec plays back, even if mute is activated in alsa mixer. This is caused by the digital_mute callback, that does not care about the current mute status in alsa mixer. As a user, I would expect, that if mute is set in alsa mixer, I don't get any output if I play something back. (But probably I'm wrong?).
On the other hand, wm8350 codec uses a flag in the driver struct, that stores the current state of mute in alsa mixer, which is taken into consideration in the digital_mute callback. But to make this possible, one can not just use:
SOC_*()
for example, but has to create a put-function using:
SOC_*_EXT()
only to get and store that flag. Is this really the way to go, or did I miss something?
Thanks, Pascal
