Reverting this one helps.
This one introduced even more wrong volume information on some codecs. Pleasy try this patch on top:
Argh! There is always a reason why we should define a constant. I applied the fix now.
This explains why the old patch worked on Colin's machine. His codec chip is different (STAC9200?), and it doesn't go in this code path but has a static Master volume creation.
thanks,
