Hi Folks,

Every once and a while, audio on my t400 (with XP) gets really strange, choppy and garbled. Sometimes I just wait for a few minutes and resolves, sometimes it doesn't. Sometimes using a different program works better. It's strange, and haven't been able to find a pattern, though I suspect it might happen with the CPU is busy? But that's a total stab in the dark. Anyone else have this issue? Any ideas?

Thanks,
Allie

FYI - the problem seems to have been fixed by uninstalling and reinstalling the conextant driver. We'll see if that fix holds...

EDIT - Nope. Still having problems. It often happens when waking up after going on standby. What a pain.

Please, have a look here:

Unfortunately, I think there has been no solution yet. At least you are not alone. The first one is my thread. There are two *.wav files in the first post of it. One is that is "choppy", the second is normal for comparison. Please write back here if that applies also to you.

yep! i have the same choppy audio issue. there was a big discussion about it over in the t60 forums on lenovo's site. they haven't fixed @#$!. It's related with DPC latencies - you can download a latency checker to see. my issue is reproducable after the computer wakes up from being on standby. a real pain. too bad this is only one of a few issues.

There is a simple for (that worked for me anyway), upgrade your intel matrix storage drivers to version 8.8 or higher.

I think this is the link.

The version on the lenovo site is old, and seems to have latency issues.
