Load it into VirtualDub.
Set "Video" to "Direct Stream Copying".
Set "Audio" to "Full Processing Mode".

Under the "Audio" tab, select "Compression" - Put a checkmark next to "Show all formats". Select the same format, frequency, and sampling rate (e.g. MPEG3, 44,100Hz, 128Kbps) as the original .AVI.

Under the "Audio" tab, select "Volume" and increase to the desired percentage.
