I have Redhat 9 and have installed RealPlayer-10.0.2.608-20041214.i586.rpm. I can use CD Player and Audio Player to listen to sounds. I can play audio or video without a problem, no errors, just no sound. What would be the problem?

If it's anything like typical, there are dozens of workarounds -- some of which actually work. The easiest solution, which the hardcore dudes consider a copout, is what I did.

I dropped in on my Geek Squad buddies at the local Best Buy. Over recent years, I've probably thrown away 3 short audio cables designed to connect your CD drive to the motherboard -- because Windows and Mac boxes both communicate that info through the bus. Unix and Linux don't. A 26" 4-pin connector cable runs $7-15 -- unless you weasel one from a friend who has dozens left over from CD drive installations in WXP boxes.

Check your motherboard manual or call the vendor [PC or m'bd] and find where to connect.

Solved my similiar problem in about 45 seconds!
