Bug #: 42957
Summary: avoid sample rate conversion when hardware supports it
Classification: Unclassified
Product: PulseAudio
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: medium
Component: core

It looks like when hardware is initialised the sample rate is kind of fixed
even though hardware are capable of multiple sample rates.
Therefore I think it's better to act on first come and fist serve dynamic
sample rates mode if the hardware can support it. For example if 44.1K audio is
being sent to pulseaudio then if the hardware supports 44.1k sample rate then
it should use 44.1k sample rate and while minutes later if a 48K audio is being
sent to it and as the same time 44.1k audio is being played then the 48K audio
should be re-sampled to 44.1K.
This way we can have the best available audio quality and at the same time to
avoid SRC which is painfully slow on embedded devices.
