I recently reformatted and decided to try the Pax drivers on my Forte, previously I had been using the stock drivers. Everything was fine for a few days, but it seems I now have intermittent loud popping and screeching coming from my sound card. It seems to happen only when I have sound playing (with no pattern I've recognized so far), and it comes out over both the amplified and non-amplified jacks. It isn't affected by changing my volume in Windows (loudness stays the same). The screeching seems to happen on and off for a few seconds/minutes and then goes away. I tried reinstalling the drivers and had the corruption again a day later. I've been using entertainment mode, with the crystalizer enabled and set to 30%. I have 5.1 selected but in Windows I have disabled the rear pair. These are the same settings I used with the stock drivers. Any ideas? Anything I can check? I'm probably going to try 1.35 drivers, but I'm not sure what has changed... EDIT: Also, headphone detection doesn't seem to work on the amplified jack. Is that how it's supposed to work?
