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! Gabucino
