[CentOS] RealPlayer10 on CentOS5 / i386

Hi,

I've installed what I believe is the latest realplayer direct from
www.real.com and I'm getting silence. Video works- but no audio. No
error messages anywhere but just silence. The Adobe flash player
plugin works in Firefox ok, so I'm guessing the error is within my
realplayer settings.

The file that I've downloaded is RealPlayer10GOLD.bin and help/about
reports version 10.0.8.805 (gold).

In tools/prefs/hardware I've tried disabling 16-bit sound, and
disabling custom sampling rates - neither seemed to make any
difference.

Anyone else got it working?
