I had a problem with getting any sound from a Windows 7 64-bit guest in Virtualkbox 3.0.10.
I solved the problem with help from members here by downloading the correct (I think) AC'97 drivers from the RealTek site.
However while I now have sound it appears in only the left channel.
The device details are
Realtek AC97 Audio
Driver details
version 6.0.1.6305 dated 19/06/2009
Driver files
Alcmv64.exe
CPLUtl64.exe
SOUNDMAN.exe
dmk.sys
ksthunk.sys
portcls.sys
RTKVAC64.sys
RtkAPO64.dll
RtkCfg64.dll
RtPgEx64.dll
SysFxUI.dll
WMALFXGFXDSP.dll
ALSNDMGR.CPL
ALSNDMGE.WAV
RtkCfg.dll
RTLCPAPI.dll
RTLCPL.exe

Can anyone confirm this set of files are the correct ones and what might my problem be?

Close this thread as I have found the solution.
Emabarrassingly a connector had come loose and I was only getting one channel on the host as well.
