Recommendations for misc. soundcards
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Aureal Vortex 2: (Pontscho)
			In config.h, change #define HAVE_AUDIO_SELECT to
			  #undef HAVE_AUDIO_SELECT
			OSS	: With MPEG files : defaults are ok
				  With AVI files  : -delay -0.5
			ALSA	: same

SB Live!:
			OSS	: OK
			ALSA	: (untested)
			Max kHz : 48

Gravis UltraSound ACE:
			OSS     : OK
			ALSA    : if video lags, use OSS or mplayerHQ
			Max kHz : 48

Gravis UltraSound MAX:
			OSS     : OK
			ALSA    : OK (should be)
			Max kHz : 48

ESS 688 and probably all old SB's:
			OSS     : OK
			ALSA    : OK
			Max kHz : 44.1

PC Speaker or DAC:
			OSS     : only with the new HQ timing code
			          (maybe won't work at all in the future)
			ALSA    : no driver
			Max kHz : 6 ;) (the driver emulates 44.1 maybe more)
			Driver  : ftp://ftp.infradead.org/pub/pcsp

 - MPlayer is mostly intended for OSS
 - use at least 2.4 if possible, 2.2 isn't tested
 - In case of any problems, first try to change "#define HAVE_AUDIO_SELECT" to
   "#undef HAVE_AUDIO_SELECT" in config.h , and recompile!
   (make distclean ; make)
   Your soundcard may not support querying of its buffer.
 - if sound clicks when playing from CD-ROM, turn on IRQ unmasking !
   for example "hdparm -u1 /dev/cdrom" (see "man hdparm" !!!)
   This is also recommended anyways... (for XMMS, etc...)
 - don't use your soundcard by other application ( for ex. XMMS ) !
   if you use ESD, start MPlayer with the esddsp utility !
 - Please tell us how MPlayer and your soundcard(s) worked together!
