>Number: 432
>Category: bin
>Synopsis: mixer should print out the current mixer settings by default
>Confidential: no
>Severity: non-critical
>Priority: low
>Responsible: freebsd-bugs (FreeBSD bugs mailing list)
>State: open
>Class: change-request
>Submitter-Id: current-users
>Arrival-Date: Sun May 21 01:00:02 1995
>Originator: Mike Pritchard
>Organization:
>Release: FreeBSD 2.1.0-Development i386
>Environment:
FreeBSD-current, w/sound blaster 16
>Description:
It would be nice if the "mixer" command printed out all of the
current mixer settings when run with no arguments instead
of printing the command usage. This would allow a person to check
all of the current mixer settings at once instead of having to
run "mixer vol", "mixer cd", "mixer bass", etc...for each setting
they are interested in.
>How-To-Repeat:
>Fix:
The following patch changes mixer to display all of the valid settings
when run with no arguments.
