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
Max kHz : 48
Gravis UltraSound MAX:
OSS : OK
ALSA : OK (should be)
Max kHz : 48
ESS 688 and probably all old SB's (without buffers):
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!
