  	 real. This is 'swapbuffers' when double-buffering.
  
+ 6. libao2: this control audio playing
+ 
+   As in libvo (see 5.) also here are some drivers, based on the same API:
+ 
+ statis int control(int cmd, int arg);
+   This is for reading/setting driver-specific and other special parameters.
+   Not really used for now.
+ 
+ static int init(int rate,int channels,int format,int flags);
+   The init of driver, opens device, sets sample rate, channels, sample format
+   parameters.
+   Sample format: usually AFMT_S16_LE or AFMT_U8, for more definitions see
+   dec_audio.c and linux/soundcards.h files!
+ 
+ static void uninit();
+   Guess what.
+   Ok I help: closes the device, not (yet) called when exit.
+ 
+ statis void reset();
+   Resets device. To be exact, it's for deleting buffers' contents,
+   so after reset() the previously received stuff won't be output.
+   (called if pause or seek)
+ 
+ static int get_space();
+   Returns how many bytes can be written into the audio buffer without
+   blocking (making caller process wait). If the buffer is (nearly) full,
+   has to return 0!
+   If it never gives 0, MPlayer won't work!
+ 
+ static int play(void* data,int len,int flags);
+   Plays a bit of audio, which is received throught the "data" memory area, with
+   a size of "len". The "flags" isn't used yet. It has to copy the data, because
+   they can be overwritten after the call is made. Doesn't really have to use
+   all the bytes, it has to give back how many have been used (copied to
+   buffer).
+ 
+ static int get_delay();
+   Has to return how many bytes are in the audio buffer. Be exact, if possible,
+   since the whole timing depends on this! In the worst case, return the size
+   of the buffer.
+ 
+ !!! Because the video is synchronized to the audio (card), it's very important
+ !!! that the get_space and get_delay are working!
