Cheers Ethics, i will give it a go now. Btw, i wouldnt consider your contribution to be lazy - heck, i wouldnt have known where to start, and to be honest its down to my own incompetance that i dont know what all this stuff means!
EDIT: Still nothing. Realised that i had missed the alsa library download (!), so followed the instructions and compiled from source. Running apt-get install for the drivers, libs and utils states that i have the most recent versions of all, and downloads nothing. Have run modprobe...etc with elevated privileges and as root, and have used alsamixer and amixer to ensure that the card is not muted, but have not yet got any sound out of the thing! Checked using lspci, and it is found by ubuntu, but using aplay -l does not show the card in sound devices. I have managed to find this thread in the ubuntu forums:
http://ubuntuforums.org/showthread.php?t=779837 ,
This pretty much lists the same problems. Opinion is that because this card uses a pci-pcie link chip, a bug in ubuntu means that the drivers and the card cannot be linked. One of the posters has filed a bug report on launchpad, but the site still reports that it is unfixed. Strangely enough, someone else in this thread said the card works fine under ubuntu 7.10, which strikes me as being a little odd. I may send a webnote to asus to (maybe) prompt them to do something about it, but as i mentioned earlier, its not such a massive problem for me (and onboard sound still works anyway - at least i didnt completely destroy my sound drivers in the process of experimenting
). If someone else who knows more about linux can get this to work, i would be very interested in the solution, but im afraid its got the best of me...
