Salut!
Nu vreau sa pornesc o flama, dar de ceva timp caut raspunsuri la
intrebarea : de ce a aparut pulse audio cind alsa isi face foarte bine
treaba? Ce nu are alsa si are pulse?
Care sunt avantajele si dezavantajele unuia asupra celuilalt?
Multumesc
*PulseAudio* (formerly *PolypAudio*) is a cross-platform
<http://en.wikipedia.org/wiki/Cross-platform>, networked sound server
<http://en.wikipedia.org/wiki/Sound_server> project.[...]
PulseAudio runs under Microsoft Windows
<http://en.wikipedia.org/wiki/Microsoft_Windows> and POSIX
<http://en.wikipedia.org/wiki/POSIX>-compliant systems like Linux
<http://en.wikipedia.org/wiki/Linux>.
PulseAudio is a sound server, a background process accepting sound input
from one or more /sources/ (processes or capture devices) and
redirecting it to one or more /sinks/ (sound cards, remote network
PulseAudio servers, or other processes).
One of the goals of PulseAudio is to reroute all sound streams through
it, including those from processes that attempt to directly access the
hardware (like legacy OSS
<http://en.wikipedia.org/wiki/Open_Sound_System> applications).
PulseAudio achieves this by providing adapters to applications using
other audio systems, like aRts <http://en.wikipedia.org/wiki/ARts> and
ESD <http://en.wikipedia.org/wiki/Enlightened_Sound_Daemon>.
In a typical installation scenario under Linux, the user configures ALSA
<http://en.wikipedia.org/wiki/Advanced_Linux_Sound_Architecture> to use
a virtual device provided by PulseAudio. Thus, applications using ALSA
will output sound to PulseAudio, which then uses ALSA
<http://en.wikipedia.org/wiki/Advanced_Linux_Sound_Architecture> itself
to access the real sound card. PulseAudio also provides its own native
interface to applications that want to support PulseAudio directly, as
well as a legacy interface for ESD
<http://en.wikipedia.org/wiki/Enlightened_Sound_Daemon> applications,
making it suitable as a drop-in replacement for ESD
<http://en.wikipedia.org/wiki/Enlightened_Sound_Daemon>.
PS: si mie imi displace PA si m-am certat cu Lennart pe tema asta.
