Aml is only needed if 2 audio mods patch the same file. For example using v4a and James or v4a and dts. Those 3 mods only patch audioeffects.conf and audioeffects.xml. So if using all 3 of those or 2 of those will you need aml. But if using ainur and one of those 3 without fmas, asphere or shoebox in UO then you don't need aml
