[Off-Topic?] Mixer device and controls (/dev/mixer)

[Michael B. Trausch]

I have one small question about the Linux mixer device.  I realize that
the drivers (such as OSS and ALSA) have their own standards for the mixer
and dsp devices and such, and so I'm not really sure if this is on topic
or not.  If you're still interested in my question, tho, read on ;p.

I've noticed that with some audio devices, I have a Bass and Treble
setting that I can play with (and usually do, becuase it makes things
sound MUCH better).  Why don't I have that in some devices, and is there
a way (through the kernel, or through a userspace program) to make up the
difference?  I use mpg123 to play my mp3 files, but that will change soon
as I am building myself a new installation of Linux (from the kernel on up
;p... the Distributions aren't keeping up as much as I want and I want all
my own home-built software anyway, except for X, 'cuz that's a bitch to
attempt to compile on my own).

Anyway, does anybody know the answer to that one?

	Thanks!
	Mike

I have not really looked into this but I think this option is only supported
when the audio hardware supports bass and treble.

...and in case the hardware does *not* have such mixer settings, the
right place to introduce them is probably 'esd' or equivalent.  I don't
remember if mpg123 (or its 21st-century equivalent, ogg123) support esd
but I think they do, and if not they should be hacked to.

I've just got to ask: what exactly do you feel you need for which
Debian 'unstable' is not up-to-date?  (Check http://packages.debian.org
to see what versions of things are available in 'unstable'.)  I ask
because in my experience, they have very rarely been more than a few
weeks out of date on any major software, except where a significant
architecture change was involved (such as the migration to xfree86
4.x), or a feature not deemed "ready for prime time" (BIND 9.0)..

Well, that's understandable - don't compile in support for features you
know you won't need, etc, save maybe 10% of your disk space that way..
