   Hi Liam, I did many tests and have a new idea now. The issue is caused by info function in kcontrol. The default info function return only two or one channels to user. I hooked info function in kcontrol and return correct channel number, it works with alsalib which supports max 8 channels. So I want to hook info function to fix this issue.

   But the soc-topology.c need to be refined. I have a discuss with Meng dong and we found It only allows get() and put() function can be hooked for a issue in design. you can refer to soc_tplg_kcontrol_bind_io to find hook logicality

   How about your idea? Thank you!
