[LAD] USB Sound Chip

Hello *, For a project with selfmade hardware (prototype and will be selled over my Website if it is working as I want), I am searching for a very Low-Cost soundchip since I need only Line-IN/OUT and it is only connected to the Line-IN/OUT of a GSM-Chip. Can someone tell me, which Low-Cost USB-Soundchip is perfectly supported under Linux 2.4 from scratch? Linux 2.4 must be, since there are to many embedded systems where size mather.
