<P>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.</P>
|
|
|
|
|
<P><UL>
|
|
|
|
|
<LI>if you have OSS as driver, first try with <I>-ao oss</I> (this is the default).
|
|
|
|
|
If you experience glitches, halts or anything out of the ordinary, have a
|
|
|
|
|
look at <I>-ao sdl</I> (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/).</LI>
|
|
|
|
|
<LI>if you have ALSA version 0.5, then you ALMOST always have to use <I>-ao alsa5</I> ,
|
|
|
|
|
since 0.5 has buggy OSS emulation code, and will <B>crash MPlayer</B> with
|
|
|
|
|
a message like this:<BR>
|
|
|
|
|
<UL>
|
|
|
|
|
<CODE>DEMUXER: Too many (945 in 8390980 bytes) video packets in the buffer!</CODE></UL>
|
|
|
|
|
</LI>
|
|
|
|
|
<LI>if you have ALSA version 0.9, use <I>-ao oss</I> or <I>-ao sdl</I> as you
|
2001-10-03 18:26:06 +00:00
|
|
|
wish. You can also use <I>-ao alsa9</I> as it works now, however it has many
|
|
|
|
|
problems (losing sync, disappearing audio, etc).</LI>

<P>On <B>Solaris/FreeBSD</B> systems, use the SUN audio driver with the
|
|
|
|
|
<I>-ao sun</I> option, otherwise you'll have no video, nor audio playing.</P>

<LI>on Linux, use at least kernel 2.4 if possible, 2.2 isn't tested
|
|
|
|

<LI>if sound clicks when playing from CD-ROM, turn on IRQ unmasking !

for example "hdparm -u1 /dev/cdrom" (see "man hdparm" !!!)
