Hi,
I am too inexperienced to file this, so pls excuse me. I am trying to follow
just the Documentation.

1.> Audio doesn't work properly in linux-2.4.3 pre4 (i810_audio). [Real Audio]

2.> I tried to run it with patches applied on 2.4.2 kernel. I tested with pre1,
pre2 and pre4. The problem seems to be in pre4. I tried to use a console real
player. It just pops an error saying
i810_audio: DMA overrun on send.

3.> i810_audio, RealPlayer, Sound. DMA

4.>cat /proc/version
Linuxversion 2.4.3-pre4 (root@freak.tcs-america) gcc-version-2.96 20000731
RedHAt Linux 7.0 #1

5.> Ooops.. I do not know how ??:-((

6.> use of trplayer. (A Terminal based RealPlayer).

7.>
