--- Comment #5 from Alexander Motin <mav at FreeBSD.org> ---
I don't think AZX_DCAPS_SEPARATE_STREAM_TAG is relevant here, since FreeBSD HDA
driver by default has different spaces for input and output streams.  You may
see it in hdac_stream_alloc(), where "Allocate stream number" chunk converts
global stream number into per-direction ones, which are actually programmed
into hardware.

Could somebody tell more about how exactly is sound garbled and on which output
(analog or HDMI)?  Unfortunately I don't have any NUC and so can't guess.
