[Bug 1494155] Re: [mako] pulseaudio resample methos missing src-sinc-*
Hi,
Upstream has decided to phase out libsamplerate, as speex gives better
"bang for the buck", i e better audio quality for the same CPU or same
quality for less CPU.
Ubuntu Touch is apparently ahead of schedule - but expect the distro to
stop supporting these in the future:
src-sinc-best-quality
src-sinc-medium-quality
src-sinc-fastest
src-zero-order-hold
src-linear
** Changed in: pulseaudio (Ubuntu)

Title:
[mako] pulseaudio resample methos missing src-sinc-*
Status in pulseaudio package in Ubuntu:
Won't Fix
Bug description:
I tried to change the pulse resampling on my mako to src-sinc-best-
quality and medium, to no avail.
Later i found out that the pulse shipped with mako isnt capable of
using these resampling methods.
$ pulseaudio --dump-resample-methods
trivial
speex-float-0
speex-float-1
speex-float-2
speex-float-3
speex-float-4
speex-float-5
speex-float-6
speex-float-7
speex-float-8
speex-float-9
speex-float-10
speex-fixed-0
speex-fixed-1
speex-fixed-2
speex-fixed-3
speex-fixed-4
speex-fixed-5
speex-fixed-6
speex-fixed-7
speex-fixed-8
speex-fixed-9
speex-fixed-10

while on an other system (non ubuntu touch) i get the correct
resampling methods:
$ pulseaudio --dump-resample-methods
src-sinc-best-quality
src-sinc-medium-quality
src-sinc-fastest
src-zero-order-hold
src-linear
trivial
