2.2.2.  Audio output devices

  - OSS (ioctl) driver
  - SDL driver (supports up/downsampling, esd, arts etc)
  - native ALSA 0.5 driver
  - native ALSA 0.9 driver (buggy, use OSS emulation!)
  - ESD (through SDL)
  - ARTS (through SDL)
  - SUN audio driver (/dev/audio) for BSD and Solaris8 users

			OSS	: OK
			ALSA	: no driver
			Max kHz : 48
			Driver	: aureal.sourceforge.net
			Driver2 : from here
				  (buffer size increased to 64k)

  GUS PnP:

			OSS	: OK
			ALSA	: OK
			Max kHz	: 48

  SB Live!:
			OSS	: OK
			ALSA	: (?)

  PC Speaker or DAC:
			OSS     : OK (use the SDL driver : -ao sdl)

			Max kHz : the driver emulates 44.1 maybe more
			Driver  : ftp://ftp.infradead.org/pub/pcsp

   - use at least 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!
