Takashi-san,
We tried invoking an IOCTL on /dev/mixer with command SOUND_MIXER_WRITE_RECSRC. It did not seem to invoke the put function of the kcontrol for selecting recording source (it's "Master Input Capture").
Also, can I add my own IOCTL commands and route control to their implementations?
Thanks in advance
Aditya

How did you check this exactly? Note that REC_MASK (RECSRC) doesn't
always correspond to an ALSA mixer element as 1:1 but often to a group
of elements.
