No sound on an IBM T60

Question

Hi all,
Hate to clutter the forums as this seems like a popular topic but I have searched far and wide on the wiki and found no solution. Basically it seems as if my sound card is being recognized, but no sound is coming out..... Before you ask I have unmuted the sound (via alsamixer), but I haven't messed around with ACPI. I'm really at a loss here.

Doom 3 has no sound
SYMPTOMS:
Doom 3 has no sound
RESOLUTION:
The no sound with Doom 3 issue can be resolved by changing the default bit rate in your Midi Setup from 2ch - 24bit to 2ch -16Bit.
To do this, open the Audio Midi Setup control panel in the Applications/Utilities folder.
Change "Properties For": to "Built - in Output" instead of "Built-in Mic". This will show you the Output options. The sample rate should be at 44,100hz, but the Bit rate is defaulted to 2ch - 24bit. Change that to 2ch -16Bit. Once this is changed, Doom 3 should have sound from the internal speaker without having to plug in speakers or headphones.
