2.3.2. Audio output devices

+ +

MPlayer's audio interface is called libao2. It currently +contains these drivers :

+ + + + + + + + + + + + +

General:

  oss  OSS (ioctl) driver
sdlSDL driver (supports up/downsampling, ESD, ARTS etc)
nasNAS (Network Audio System) driver
alsa5native ALSA 0.5 driver
alsa9native ALSA 0.9 driver (works, but has problems -> use OSS)
sunSUN audio driver (/dev/audio) for BSD and Solaris8 users
+ +

The fact is, Linux soundcard drivers are usually shit, and always as +incompatible as they can be. It MAY take a while to find your optimal settings.

+

    +
  • if you have OSS as driver, first try with -ao oss (this is the default). +If you experience glitches, halts or anything out of the ordinary, have a +look at -ao sdl (NOTE: of course you'll have to have a new SDL library and its +devel pair installed). It helps in a lot of cases (it also supports ESD, ARTS, and +up/downsampling. /esd is GNOME's, arts is KDE's sound daemon/).
    • +
  • if you have ALSA version 0.5, then you ALMOST always have to use -ao alsa5 , +since 0.5 has buggy OSS emulation code, and will crash MPlayer with +a message like this:
    +
      + DEMUXER: Too many (945 in 8390980 bytes) video packets in the buffer!
    +
    • +
  • if you have ALSA version 0.9, use -ao oss or -ao sdl as you +wish. You can also use -ao alsa9 as it works now, however it has many +problems (losing sync, disappearing audio, etc).
    • +

+ +

On Solaris/FreeBSD systems, use the SUN audio driver with the +-ao sun option, otherwise you'll have no video, nor audio playing.

+ +

    +
  • on Linux, use at least kernel 2.4 if possible, 2.2 isn't tested +
  • if sound clicks when playing from CD-ROM, turn on IRQ unmasking ! + for example "hdparm -u1 /dev/cdrom" (see "man hdparm" !!!) + This is recommended anyways... (for XMMS, etc...) + Read section 4.1. +
  • don't use your soundcard by other application ( for ex. XMMS ) ! + if you use ESD, start MPlayer with the '-vo sdl:esd' option ! +
  • Please tell us how MPlayer and your soundcard(s) worked together! +
