--- Comment #15 from Alessandro Ferri <alessandro.ferri at icloud.com> ---
Thanks Tanu,
You've given a lot of information I did not know. At this point, before doing
the tests that you suggested on-resample method = speex-float-1 or
resample-method = ffmpeg, I must build pulseaudio 5.0 again. So first I see if
these issues disappear. I want to ask if I have to first uninstall the previous
installation from source, and if so how, or simply just build a new one and
install it. In the latter case the procedure, from what you told me is:

sudo apt-get install libspeex-dev
or
sudo apt-get install libspeex-dev:armhf
what is the difference? I use raspberry Pi2.

after

cd pulseaudio-5.0
./configure --sysconfdir=/etc --localstatedir=/var --disable-bluez4
make
sudo make install

and at the end

sudo ldconfig

I am attaching the init script with which I run pulseaudio as system mode.

I also wanted to ask further explanation. I use shairport-sync as Airplay
emulator. The audio output of shairport-sync is fixed on pulse.
In this way I lose synchronization between Airplay devices and my raspberry. So
I wanted to ask you:

1) Is there a way to run only pulseaudio as an Airplay emulator, eliminating
shairport-sync?
2) Otherwise is there a way instead, working on the parameters of pulseaudio,
to maintain synchronization and eliminate the latency of the audio output?
