As far as I can see, the library API has no mechanism to set or clear this access right, so it's set by default to allow TLVs for controls where it makes sense. (In theory, the code could be changed to clear the readable flag when there is no TLV.) > I have a simple enumeration without TLV. I use snd_ctl_elem_write but > do not call snd_ctl_elem_tlv_write.

You'll have to write a fake TLV (an empty container).
