This adds support for all sample rates supported by the hardware,
Digidesign Mbox 3 supports: {44100, 48000, 88200, 96000}
Fixes syncing clock issues that presented as pops. To test this, without
this patch playing 440hz tone produces pops.
Clock is now synced between playback and capture interfaces so no more
latency drift issue when using pipewire pro-profile.

You put a tailing sparce superfluously.

Ditto. Try to run checkpatch.pl at the next time; it should warn you
such errors.

Let's to be classic: try to put the variable definitions at the begin
of the function.

Ditto.

You can use memset(). (Or if it were a __le32 variable, it can be
simply zero assignment.)

Strictly speaking, this won't work always as no alignment is
guaranteed for char[4]. If you need to pass/receive a 4-byte integer,
better to use a __le32 variable instead. For a one-byte temporary
buffer, you can use another variable additionally.
Could you resubmit with those corrections?

Also, put a space between Manu and Linares (supposing it's your real
name). Signed-off-by is a legal requirement, hence it should be
properly spelled.

This adds support for all sample rates supported by the hardware,
Digidesign Mbox 3 supports: {44100, 48000, 88200, 96000}
Fixes syncing clock issues that presented as pops. To test this, without
this patch playing 440hz tone produces pops.
Clock is now synced between playback and capture interfaces so no more
latency drift issue when using pipewire pro-profile.

Those two lines cause sparse warnings, unfortunately.
You can't assign int to __le32 type directly, and you can't compare
between those types directly, either.
That said, it should be rather like
if (new_rate != le32_to_cpu(buff4))
dev_warn(...);
You can check the sparse warning by yourself by passing C=1 argument
to make, too.
thanks,
Takashi
This adds support for all sample rates supported by the
hardware,Digidesign Mbox 3 supports: {44100, 48000, 88200, 96000}
Fixes syncing clock issues that presented as pops. To test this, without
this patch playing 440hz tone produces pops.
Clock is now synced between playback and capture interfaces so no more
latency drift issue when using pipewire pro-profile.
