Linux   had a   reputation  for lacking good    support for sound   and multimedia
applications    in  general.    However,    great   strides have    been    made    in  recent  years
to  correct this,   and support is  now a   lot better  than    it  used    to  be. (It might
make    you smile   to  know    that    Microsoft   no  longer  supports    the Microsoft
Sound   Card,   but Linux   users   still   enjoy   support for it—no   doubt   just    to  annoy
the folks   in  Redmond.)   UNIX,   however,    has always  had good    multimedia
support,    as  David   Taylor, UNIX    author  and guru,   points  out:
The original    graphics    work    for computers   was done    by  Evans   and
Sutherland  on  UNIX    systems.    The innovations at  MIT’s   Media   Lab were
done    on  UNIX    workstations.   In  1985,   we  at  HP  Labs    were    creating
sophisticated   multimedia  immersive   work    environments    on  UNIX
workstations,   so  maybe   UNIX    is  more    multimedia  than    suggested.
Limitations in  Linux   support doesn’t mean    UNIX    had the same
limitations.    I   think   it  was more    a   matter  of  logistics,  with    hundreds    of
sound   cards   and thousands   of  different   possible    PC  configurations.
(Reprinted  with    permission  by  Dave    Taylor)That    last    sentence    sums    it  up  quite   well:   UNIX    had a   limited range   of
hardware    to  support,    whereas Linux   has hundreds    of  sound   cards.  Sound   card
device  driver  support has been    long    lacking from    manufacturers,  and there   is
still   no  single  standard    for the sound   subsystem   in  Linux.
In  this    section,    you learn   about   sound   cards,  sound   file    formats,    and the sound
applications    provided    with    Ubuntu.
Sound Cards
Ubuntu  supports    a   wide    variety of  sound   hardware    and software.   Two models
of  sound   card    drivers compete for prominence  in  today’s market:
    ALSA,   the Advanced    Linux   Sound   Architecture,   which   is  entirely    open
source
    OSS,    the Open    Sound   System, which   offers  free    and commercial  driversUbuntu  uses    ALSA    because ALSA    is  the sound   architecture    for the Linux
kernel, starting    with    the 2.6 series, all the way to  the current 4.x series. OSS
might   still   be  found   here    and there,  but it  is  no  longer  in  widespread  use and
should  be  considered  deprecated.
ALSA    supports    a   long    list    of  sound   cards.  You can review  the list    at

Ubuntu  detects most    sound   cards   during  the original    installation    and should
detect  any new additions   to  the system  during  boot.   To  configure   the sound
