[Buildroot] [PATCH 1/2] package/alsa-plugins: fix dependencies for the alsa plugin package

[Charles Hardin]

The alsa-utils will remove and create the /usr/share/alsa dir
as a whole and since the alsa plugins needs to add config into
this same directory it should come after those install steps.

Also, the bluez alsa needs the plugins installed to find them
during the configuration phases - so, interlock the plugins
when configured.

[Buildroot] [PATCH 2/2] package/alsa-plugins: require libsamplerate for the plugins

[Charles Hardin]

During the execution of the alsa plugins on a test application,
the library would not function without samplerate being enabled
and present. So, this is a patch to just include the samplerate
since the latest versions seem to require it for the plugins to
work.

There might be another fix instead of this patch, but this got
the sound to play for the bluez alsa stack as expected.

  It doesn't sound unreasonable that some plugins require samplerate, but it 
seems unlikely that none of them work without libsamplerate...

  If it's just for bluez, then it sounds more logical to do it in bluez-alsa?

[Buildroot] [PATCH v2 1/1] package/bluez-alsa: allow a samplerate conversion for audio playback

[Charles Hardin]

In the case of the bluetooth audio then incoming stream will be coming
from bluetooth devices at varying sample rates like (44.1, 48, 96, 192 kHz)
and the odds of a sound device matching that samplerate exactly
is a bit slim. So in the case of a bluez audio playback the system will
need to do a samplerate conversion.

Thus when enabling bluez-alsa and the alsa plugins select libsamplerate
to support the shift from the incoming samplerates to an often fix-rated
audio device.

I've added a small comment in the Config.in file to explain this
select, and applied. Thanks!
