Hello Takashi Sakamoto, Takashi Iwai, Andrew Chant, Thank you for the discussion. I saw the drawbacks of my proposal, and it was nice to clarify them with you. Also, during our discussion I found, that the "description of playback switches" has a different solution. I will check my new idea. If it will work good enough, I will send a patch later. >From my perspective, we can consider this RFC to be closed. Thanks for your attention.

One of the problems is solved. However, the second problem is still actual. >>> As you had a recent experience with alsamixer, what is your opinion? >> I think Kirill mentions a patch to change the type of 'iface' for such control elements to 'SNDRV_CTL_ELEM_IFACE_CARD' or 'SNDRV_CTL_ELEM_IFACE_PCM', but I cannot find such patches in Iwai-san's tree[1]. I guess they're not merged yet. > Andrew mentioned the patch [2] > >> In my humble opinion, if so, Kirill's patch is not better in a view of compatibility, because such smixer controls suddenly disappear via alsa-lib's mixer APIs when the patched kernel is released. In a point of backward compatibility, this kind of change should be avoided, as possible (of cource, depending on the cases). > The patch of Andrew and my RFC serve different purposes.
