Webreturns the diff between 'hw_ptr' and 'appl_ptr'. The SNDRV_PCM_IOCTL_DELAY is called only for cases where the control structs cannot be mmap'ed, and the result is the same anyways. On the kernel side, drivers just implement the "pointer" method returning one value (-> hw_ptr). This tells the delay to last transfer from ringbuffer to/from HW, http://www.rpmfind.net/linux/RPM/opensuse/15.5/x86_64/kernel-azure-optional-5.14.21-150500.28.2.x86_64.html
