Latency Issue

marvintpa said:

Whenever I try to use analogue LINE IN on my Windows 7 machine there is latency,- it's quite marked. It doesn't matter whether output is wired or optical.

This used not to happen but now it does: this does not appear to be a sound card issue as I have tried three different ones to the same effect.

Everything else works,- playing audio is fine. Can anyone suggest what else might be causing this?

The audio which is input is fine,- it's just the monitoring of it which is delayed by .25 second.

May just be a driver. Use this to check them. DPC Latency Checker

Hi : thanks for your reply. Yes, I tried this,- all green and "should be able to handle.." etc.

Perhaps re-install audio driver?

Also to check you OS run a system file check

Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW

Read here for more information SFC /SCANNOW Command - System File Checker

Let us know the results from the report at the end.

Hi Zigzag: thanks for that idea: "..did not find any resource integrity issues" or similar. As to re-installing the card, I've done that numerous times (and with three different devices); I'm toying with re-installing Windows 7, adding the card drivers first, then proceeding by a process of elimination, -ending perhaps with the purchase of a Mac..!

Ah, but as stated at the outset, my system worked with unnoticeable latency for more than a year before the current issue began..

The card in question was actually a USB external SB Audigy 2; since things went wrong I've tried to use two other external USB cards (SB XFi and Terratec) and now an internal SB XFi,- to no avail. I used to be able to listen to a backing track and play along with it but now it has become difficult.

I'm not sure whether or not this is relevant but I think that the people who supplied the barebones kit had overclocked it and recently I had to replace the BIOS battery.. I wonder whether they had tweaked settings which have an effect on latency (if this is possible)..
