I'm having some issues with the same driver downloaded from Dell. I use Ventrilio voice chat for gaming and one day the input up and decided to stop working. Because the output worked fine I assumed it was an issue with the cheap headset I bought, so I went and got another...same problem. I google the problem, find the CORRECT driver from dell for the E1505, and now I have no audio what-so-ever. Anyone have any suggestions?
