Also, it is possible that the sound card/chip is NOT connected to the PC speaker. Most (all?) laptops / notbooks / netbooks / tablets do include speaker(s) connected to the sound card/chip. Most (all?) *desktops* do not -- they require *external* speakers ("sold separately") to be connected. Since this calls itself a "Mobile Workstation", I am not sure how things are connected. Is "Mobile Workstation" 'fancy' terminology for "laptop" or is it something else? Is this a 'lugable' machine (eg a desktop with a carrying handle and built-in monitor)? > > > > > Any assistance or direction would be appreciated. > > > > David > > > > > > _______________________________________________ > > CentOS mailing list > > CentOS at centos.org > > http://lists.centos.org/mailman/listinfo/centos > > > > > -- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments
