G'day ASLA Developers I am hoping that someone might be able to assist me with an audio issue I am having. Recently I have begun using the Dell T3500 precisions as an Video Conferencing machine (using the Access Grid and EVO Software). Information on hardware specs, etc can be found at http://www.alsa-project.org/db/?f=7f33770c89802b0ab3132f21914cc6ca7f6626 37 Unfortunately, I have issues when using either a clearone Chat50 or Chat150 (these are essentially speaker phone devices [See http://www.clearone.com/products/product.php?cat=9&prod=94 for device description]) with the speaker audio being distorted and static, cracks and popping type sounds being introduced. The microphone audio quality is fine. These issues were seen using Fedora 10 and Fedora 11. I tried upgrading to the latest ALSA drivers and "testing" kernels without any success (on a previous Fedora 10 install). It was found (still in the initial stages of testings) that if I plugged the Chat50 device into a USB hub, rather than directly into the Machine, the audio issues disappeared (at least for some of the software). It should also be noted that I have a number of Dell T3400 series machines that don't experience these issues. Additionally is should be mentioned that the T3400 uses the ICH9 chipset family whereas the T3500 uses the ICH10 chipset family which includes the USB controller. Just wondering if there is anything I can do to resolve this issue? Many thanks in advance, Jason. -------------------------------------------- Jason Bell, B.I.T.
