Hello all, I have posted a version 2 of the LinuxPPC dmasound back-port from V2.4.0-test4 to 2.2.17pre10-ben2. Patches against this and 2.4.0-test4 (to add a bit more info about record buffers on the AWACS) can be found on: http://www.drfruitcake.com/linux/linuxppc.html along with explanations etc. Basically, there is now a single code-base with KERNEL_VERSION() conditionals... There is also a temporary (I expect) patch there that will get sound working on G3 Minitower & desktops under 2.4.0-test4. It is not especially elegant... but it will get you going again. Thanks to those who have tested so far - particularly Gwyn Judd. Also thanks to Ben H & Geert for putting up with my dumb questions... have fun, Iain.
