Is. I'll work on it. For now, just add support
for one converter.

an use a rate bitmap to be more precise in "struct
snd_codec_desc_src" (or combination of range/bitmap).

Interesting, that&#
ate Shift 10" control implementation in
sound/drivers/aloop.c. It would be nice to have the base offset for the
shift/drift/pitch value standardized.

to the card, but the
element identifiers have already iface (interface), device and subdevice
numbers. We are using controls for PCM devices for example. The binding is
straight.
Just add SNDRV_CTL_ELEM_IFACE_COMPRESS define and specify the compress device
number in the 'struct snd_ctl_elem_id'.

x27;simple EQ', the parameters should be
the band (frequency range) volume values. It's abstract and the real filters
(resp. implementation) used behind may depend on the hardware/driver capabilities.
From my view, the really special cases may be handled as black box, but
others like (A)
type and an opaque set of
parameters with this UUID passed in a header.
We don't need to use UUID-defined scheme for simple (A)SRC implementation. As
I noted, the specific runtime controls may use existing ALSA control API.

I was thinking of loopback with endpoints using compress streams,
without physical endpoint
I like this idea.

We can eventually add new ioctls to the ALSA's control API (/dev/snd/control*)
for this purpose (DSP processing).

ne subsystem where is the driver code placed. I
also see the benefit to reuse the already existing framework (but is v4l2 the
right one?).
