[Àû¿ë´ë»ó: 0.74_SVN_new, DOSBox-x]

 Amount of time in nanoseconds the DSP chip signals 'busy' after writing to the DSP (port 2xCh). Set to -1 to use card-specific defaults.

WARNING: Setting the value too high (above 20000ns) may have detrimental effects to DOS games that use IRQ 0 and DSP command 0x10 to play audio.

Setting the value way too high (above 1000000ns) can cause significant lag in DOS games.
