I want to add the results of a few simple tests:
1. Reverting only linux-2.6.25-rc6/sound/pci/hda/hda_intel.c to the
2.6.24.2 version had no effect (sound was still very quiet).
2. Reverting linux-2.6.25-rc6/sound/pci/hda/*.[ch] to their
2.6.24.2 versions worked (i.e., sound was lound again).
3. Other quick attempts at reverting various subsets of
linux/sound/pci/hda/*.[ch] have resulted only in compilation
errors.
