That's exactly the change I committed to the ac97 mixers about a year
ago. The issue is, it's very hard to do that with stateless mixers,
and I can't say I'm really satisfied with the result, but at least it
allows OSS applications to work to some extent in some situations.
Jukka said he didn't know any up/down applications. I know two of
them: mp3blaster and mplayer.
Both had the issue that the granularity of their own mixer change was
not enough to allow the volume to be pushed up, so I added a guess in
ac97.c to actually change the volume in that situation.
But I let you look at the downside of this:
for i in `jot 45 150`; do mixerctl -w outputs.master=3D$i; done
