Inspiron 9400 bad sound

I just installed windows 8 release preview on my inspiron and the sound coming out of the speakers is really bad. The stock win 8 doesn't give me much options on adjusting the sound (bass and sub loudness ect) and I know it is capable of way better.

Is there a program or setting out there that will customize it allot more than what I can now? HELP!



Windows 8 has backwards compatibility so other os programs should works also.
