I found this in BT's nessound.txt:
Is this delay something that really needs to be emulated? I don't see how it would make any difference.... Haha, but then again (for some strange reason) I wouldn't be surprised if some games actually relied on this "feature" somehow.
Pz!

After resetting the 2A03, the first time any sound channel(s) length counter contains a non-zero value (channel is enabled), there will be a 2048 CPU clock cycle delay before any of the sound hardware is clocked. After the 2K clock cycles go by, the NES sound hardware will be clocked normally. This phenomenon only occurs prior to a system reset, and only occurs during the first 2048 CPU clocks after the activation of any of the 4 basic sound channels.
