In the hope that it helps, the initialization of the Audigy 2 ZS
Notebook still succeeds on my laptop, but it does seem noisier then
usual lately (this writing to ADC failed message):

This is a ThinkPad X41.

Also, I would like to say that although this card works on an x86
laptop, it has severe difficulties in a PowerBook. In that machine it
can not be hotplugged, and needs to be inserted before powerup, and
removal with the power on results in a kernel oops.

Before I forget, this is on vanilla:
Linux deep-blue 2.6.22-rc5 #1 Sun Jun 17 23:23:55 BST 2007 i686 Intel(R)
Pentium(R) M processor 1.60GHz GenuineIntel GNU/Linux

If I can help by giving you more information, let me know.

Tony V.
