Mandrake 10 usb audio

[suicidal_orange]

I have recently installed mandrake 10 and overall it seems very good. The default kernel even supports my philips USB hifi, something i never thought would work under linux.

Unfortunately the default kernel bootsplash doesnt work, and if i try to compile the ATI drivers it says "invalid module format" so I made my own kernel, the bootsplash works, the ATI drivers work but the hifi doesnt.

Well, It kinda does, the hifi itself says its connected and ogg123 managed to play something out of it once, but its not listed in xmms as it is on the default kernel.

While I dont consider myself to be a newbie to linux (ive been playing around in it for over a year) I cant work out what I need to look at while running the default kernel to get the config for the hifi, lsmod lists some modules for it, but ive tried compiling these as modules and built into my custom kernel and it doesnt seem to work. Of course there is always the possibility that it is working, but not making its device obvious enough for me to work out which it is, as it uses the onboard AC97 as the default audio device.

If your still reading I guess you know something, and i appologise for the length of this post, but any advice would be great. UT2004 would be so much better with decent speakers .:)

look at the config files for both kernels and see what differences there may be. Also, would this use a module, which module and is it loaded?

On the mandrake kernel it is all modules, but ive went through both configs at the same time to look for differences in all the sections i see as relavent, but there must be some link to an obscure section (not usb or sound). Maybe something like i2c is involved? im just not sure how to get all the information i need even though it is at my fingertips.

I now have everthing working, but only if i switch the usb hifi on once X has loaded. Not sure why, but if I boot with it on lots of @'s are echo'ed all through the boot sequence, and no audio works, not even the onboard. In an attempt to fix UT2004 to make it run I have changed the kernel, tried diffferent driver versions and even upgraded to x.org, but it still wont load. I know this topic has been beaten to death on every forum so I wont ask any further, but thought the USB audio info might be of some use to someone, as there is very little documentation anywhere online about it.
