Hi Bob -

Your idea about changing ./include/asound.h line 423 to read

#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 1)

did get it to compile, thanks very much.

The good news continued as I was able to modprobe the new snd-intel8x0 driver 
into the kernel (after a make install of the alsa stuff), and it seems to 
operate okay.  That's the native motherboard sounds system on this laptop 
taken care of.

However when I tried to modprobe in the new usb-snd-audio, I get the following 
complaint

[root fastcat alsa-driver-1.0.2]# modprobe snd-usb-audio
FATAL: Error inserting snd_usb_audio 
(/lib/modules/2.6.1-1.65/kernel/sound/usb/snd-usb-audio.ko): Unknown symbol 
in module, or unknown parameter (see dmesg)
[root fastcat alsa-driver-1.0.2]#

Here is the relevant part of /var/log/messages -- its a bit noisy with my 
multiple attempts, but I left it as is in case it is meaningful

I checked in an existing kernel module with strings, ide_cd.ko, it does not 
have versioned kernel symbols and neither does the new snd-usb-audio.ko, so 
that's not the problem.

Andy more ideas?
