Hello François, the driver is located in: /dev/audio/old/cs.../0. Are there any plans till the release of R1 to support old drivers like this one? I don´t have a internet connection all the time right now so I couldn´t search for source code or more information. If I have new information I´ll post it here.

API). find -type c /dev/audio if you see /dev/audio/old/cs.../0 then it's an old API driver. While it should still load and publish devices, the legacy media node that is supposed to use it is not finished. If you see /dev/audio/multi/cs../0 then it's an R5 multi_audio, but Haiku has a different version of multi_audio, so it might not work either... Does this driver come with source ? Where did you find it ? François.
