Hello, The fine folks at Echo have finally released their open source driver library. They used the MIT license with one extra non-endorsement clause. I'm not a lawyer but it looked plenty compatible to me so I checked the sources in: current/src/add-ons/kernel/drivers/audio/echo/ generic I also started work on two drivers based on these sources: one for the "echo gals" family of cards, and another for the "echo 24" family of cards. I have myself an echo darla (one of the echo gals) so working on this is a natural for me. I invite anyone else who is interested to contribute, although maybe waiting a little while may be in order. (I just got started 5 hours ago.) I also checked a nice pdf that explains how to use the library. Since it seemed like documentation I put it in: current/docs/develop/media Nothing building yet, I'm too tired to work on it atm. :-) BTW, thanks to marcus for the ich driver which I've already started cannibalizing. :-) Andrew
