Sound Lag

In the DeSmuMe 0.9.6 installment, I have found that most sounds repeat and music seems very choppy. I have checked through the FAQ and relevant seeming topics on the forum, but nothing so far has worked.

For instance, I have tried changing the Synchronization Mode in Sound Settings to Synchronous, Synch Method "P", which does fix the sound repeat, and the game runs at normal speed, but the music lags by about 3 seconds. I have also tried changing Interpolation from Linear to None, but the music still lags by about 2 seconds. The frame rate and game speed stay the same.

Could someone point me towards a possible solution? Thanks.

Re: Sound Lag

P is laggy. Z and N are less laggy. If the game is running at 60fps then N and Z should not sound bad at all.  But if the game is running slow, they will sound crusty and poppy. You may try changing the sound setting to "dual spu" which may sound good, or may sound terrible, depending on the game. If your game is running substantially less than 60fps, and sounds bad on dual spu, then you are out of luck. Interpolation mode doesnt affect lag.

Re: Sound Lag

You know what else REALLY helps? In the sound settings, turn up the buffer size to 999999999 (the highest it will let you go).

Re: Sound Lag

Yeah, it helps your sound lag by 5 seconds.

Yeah, I noticed that. sad Atleast it sounds smoother though.

What if I had a super-fast gaming computer, would the sound still lag?

Re: Sound Lag

yes. where you read "sound buffer size" you may oftentimes, and certainly in this case, interpret it as "intentional lag to prevent buffer underruns". by making a big buffer you make a big lag. it is the same thing.

Re: Sound Lag

I turned up the lag to 9999999 and this time it didn't lag, and without sound lag... I guess my computer is border-line fast enough and the fresh restart helped out. I really need to buy an Alienware.
