I've just rebuilt my kernel to include USB support and now my sound card has stopped working. I've searched for the error message on the web but haven't come up with anything much.
I wasn't aware that I'd changed anything other than the USB settings (I used 'make menuconfig').
Was your previsous kernel a vendor supplied on (RPM or deb etc)? If so then you need to find the right .config file for it and use that as a starting point for your new build by copying it over the .config in your kernel sources. If you don't do this then the configuration you start with in menuconfig is not the same as the currently installed kernel so just changing some things won't work.
As I'm writing this from work I haven't got all the info to hand at present but I'm using the 2.4.18 kernel with ALSA 0.9.0beta12. (hmm... wonder if it would be worth seeing if there's a later release of ALSA? wonder if it would make any difference?)
My sound card is a Creative Soundblaster 128 PCI (chip show up as an Ensoniq 5880 AudioPCI) and I've been successfully using the ens1371 driver.
As a side issue my NVidia drivers also hiccupped when I rebuilt the kernel but were OK after I rebuilt the NVidia package. Should I have needed to do this or is there something else I'm not doing and should?
Sorry, I know I should be supplying a lot more info. but I'm hoping this might be a 'no brainer' type newbie error (oh look! all those bacon flavoured objects flying past the window!! :o) )
I hope I haven't underestimated your experience on kernel compilation but you do say that you are a newbie.

Sorry, should have said. This is a LFS system so all my kernel builds are home grown. I do a save to and restore from a specific .config for each build so I'm happy that I was amending a known baseline. ____________ CONSOLATION, n.

Cracked it!! A case of RTFM I'm afraid to say. In the config I'd configured the kernel to generate the drivers for my sound card and OSS - wrong!!. The ALSA documentation does say very clearly that you should specifiy sound support but NOT select any devices or OSS.
I took them out and re-genned the kernel and it all burst back to life! Oh well, at least I've upgraded to the latest NVidia and ALSA releases.
Interesting side issue, the NVidia docs say that you have to do a make install every time you rebuild the kernel or it won't work. I could've sworn I'd rebuilt a kernel without doing this and had no problems.
