Takashi, Jaroslav,

could you please explain what exactly snd_pcm_delay() returns?

Some applications (such as WINE) assume it is the time that would pass until we reach an underrun if we would stop writing any further data to the PCM device.

<WRONG>

Other applications (such as most media players) use it for time synchronisation. i.e. assume that it is the time that passes until a sample I write to a PCM device now would take to be played.

<RIGHT>
