I just deleted all the media cache files and let the program rebuild from scratch and I's still having the issue. in fact, after I do the gain adjustment, the affected clip almost looks likes its jittering ever so slightly on the timeline during playback. This has never happened before. I have made no changes to my computer for me to think ti was somethgin I could have done

Per Jim's link, I'm using CS 5.5.2, Mercury accelerated, system is an i5 2500k, gtx 560 ti and 4 gigs of RAM.

The audio meters dont work when playing back.

One thing I just noticed is that I had an internet radio playing in the background and when I did the adjustment just now and playe dit back, the audio from that web browser cut out as well.

Im using Premiere WDM sound in the sound options. I tried ASIO as well and same thing is happening.

Tried that Jim, still nothing. Makes no sense. I have no idea why this would just happen out of the blue. Happens on any sound clip in which i tweak the gain. Ugh. Going to update the Realtek audio drivers, will report back tomorrow

OK So i found out what the deal is. This audio has 2 tracks. I am hilighting both tracks when adjusting the gain. there is no waveform on A2. if I adjust only the clip witht he waveform, it works fine, hilighting both causes the error, but the waveform on A1 doesnt change at all. I dont recall this ever happening prior to recently. Now if I want to adjust the gain, I have to unlink the audio and vide tracks to separately hilight only A1 when making an adjustment.

Hey Bill, but when I perform a sucessful gain adjustment, the waveform has always changed in size to reflect the decibel change.

I think you might be confusing volume levels (yellow bar across audio clip) with the gain levels (how high or low the waveform is on the clip.). In cs5.5, any time I adjusted gain on the audio level in the timeline, the waveform gets larger or smaller on the clip to show adjustment.
