I built a PC for a customer that includes an NEC 2500 DVD burner and a Liteon LTC-4816H DVD/CD-RW.
I used an ABIT VT7 MoBo (VIA PT880 chipset) with a 3.0GHz HT CPU w/512MB Mushkin DDR PC3200.
Both optical drives play audio just fine from an Audio CD (MP3 or wav), or a DivX file.
Anytime I insert a DVD though, the audio won’t play. The audio won’t even play through DVD Shrink’s preview.
I’ve tried using audio cables or not. I’m using an ATA/66 IDE cable.
I contacted the ABIT newsgroups, and ABIT support, but my inquiries went unanswered.
