i dont know where to post this sound issue, so i post here
this happened 1 week ago, and ive been using my laptop for a year...
its got delay/lag for 0.5s from any sound (music player, video, sound from game too..)
my laptop is asus N46VZ , and i currently reinstalling windows 1 week ago..
this never happenend before, is it driver or hardware that makes it like this ???
i doubt its from spdif output headset, because i listening from headset, and ive tested if i dint use headset the problem didnt occur (probably, because i test it not long enough..)
need solution

Could you provide more details on "its got delay/lag for 0.5s from any sound"? Does it mean that you getting delays randomly while playing sound or does it mean that audio starts playing 0.5s after you start it and then continues playing smoothly?

im getting delays randomly...
not delay on start then smooth, but it really random...
it could this one day smooth without delay/lag, but sometimes it will delay, i dont know what causes it.
 
In that case, it might be a good idea to have xperf log. Could you please run Windows SDK setup and select to install "Windows Performance Toolkit"? Once it's installed run the following command from elevated (Run As Administrator) command prompt (if the command asks you to modify the registry, please do that, reboot your computer and re-run the command):

Code: 
xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular

Now, play some audio until you experience the lag issues you mentioned. Once you do, run the following command to stop the logging:

Code: 
xperf -stop -d C:\CPU.etl

Compress C:\CPU.etl log file and attach it here.

Thanks.

It doesn't matter. Windows Software Development Kit 8.1 is the newest version and it works perfectly on Windows 7 too.
 
ive already run the xperf for about 6-7 days..
but it seems the problem have not been seen again...

oh one more thing, can i change the command to stop xperf , from [xperf -stop -d C:\CPU.etl] to [xperf -stop -d D:\CPU.etl] ?
i changed the directory of CPU.etl , to save it on D instead of C, because im using SSD on my C ...
thx b4
 
Hello,

you shouldn't be running xperf for so long. It should be ~15 minutes maximum, otherwise the data in the trace is likely to be lost. Anyhow, we must sure that there were issues during these 15 minutes, otherwise the trace log won't help much. In your case, it might be difficult, since you mentioned that sometime these issues occur and sometimes they don't.

As for the command, yes, you can change C:\CPU.etl to whatever path you want.

ah i c , so only activated it when the problem occurs within 15 minutes , then stop the xperf log ? then ill stop it now...
and , when the xperf log is activated, does the size of logged xperf will growing ?? does it take up much space ? bcause it still on 1 week++
thx

sorry, just now, when i tried to shut off the perf log...
it mentioned something...

It uses memory while running. Once stopped, it flushes contents from the memory to ETL file.

The process should be something like this:

  1. You see the issues with sound started
  2. You start xperf
  3. You make sure the issues continues
  4. You stop xperf
