Some more comments on using all packs together.
When one has both sound packs, and also uses 3rd party modem and TV (tuner) packs, then one will most likely again find duplicated sound chip HWIDs.
Many Modems have sound functions, and old timers know that one could stare at a unknown device after the sound driver was installed, and when the modem was installed everything suddenly worked. We went like "hey? I have two sound devices now". The Serial Comms Sound device caused a "yellow flag or the unknown device Question mark" and it would often cause the real soundcard to not make a peep..
TV-tuner cards will install some sound capability as well.
What I am saying is that it could be better to have ALL than to have too few.
