The spec file applies the patch (that's what the %patchXXX macro does)
while cd'ed to the package main directory (ie: alsa-driver-0.9.x in our
case). There is no file named hdsp.c there and that's why patching
fails, so you have to edit the patch so include the whole path to it, as
in this example:

--- alsa-driver/alsa-kernel/pci/rme9652/hdsp.c.0.9.6	2003-07-18
12:04:59.000000000 +0200
+++ alsa-driver/alsa-kernel/pci/rme9652/hdsp.c	2003-08-16
16:14:18.000000000 +0200

[you also have to edit out one chunk as the 0x32 device id is part of
current alsa, otherwise the patch process fails on that chunk]

I tried to build both on 0.9.6-2.cvs and 0.9.7-1.cvs (as yet unreleased)
and the build fails, the patch does not appear to be compatible with
either release. This is where it fails:
