I have problems making my LiteOn 811S (Pacific Digital) to play sound from DVDs. I am puzzled. I replaced the Samsung CD-ROM in my Dell Poweredge 600sc with the LiteOn 811S (Pacific Digital U-30201-RV1 Mach-8). I connected sound cable to the sound module (on board soundcard - Intel/SoundMAX) in the same way how the Samsung CD-ROM was connected yet I do not hear sound when playing DVDs. Aside from that everything works just fine.
My motherboard is a proprietary version of Intell D875PBZ (http://www.intel.com/design/motherbd/bz/) used also in other Dell Percision 360 (http://docs.us.dell.com/docs/systems/ws360/en/ug/dabout.htm#1109228)
I emailed Pacific Digital support couple days ago and have not heard from them so far. Any ideas what is wrong and how to fix the problem? Thanks in advance.
