Why can't direwolf use the default audio chip of the raspberry Pi ?

In order to only decode afsk ?
If it is possible what should i put in direwolf.conf ?

For starters, github is for bugs and issues with Direwolf. Questions should be asked in the Yahoo group. https://groups.yahoo.com/neo/groups/direwolf_packet/conversations/topics
As for the Pi, it supports outgoing audio. It was not built for input audio, hence the need for a sound card.

yes but if I want to use direwolf only to decode ?

Then you need to buy a sound card.
