.SH NAME
alsaconf \- configuration tool for the Advanced Linux Sound Architecture
.SH SYNOPSIS
.B alsaconf
.RI [ options ]
.SH DESCRIPTION
This manual page documents briefly the
.B alsaconf
command.
This manual page was written for the Debian distribution because the
original program does not have a manual page.
.PP
\fBAlsaconf\fP is a simple shell script which tries to detect the sound cards
on your system and writes a suitable configuration file for ALSA. It will try
to guess what GNU/Linux distribution you're running, and will act accordingly
to the standards of that distribution, if specific support is available.
.PP
Alsaconf will write a modutils snippet which can be then used by modutils
to load the correct parameters for your sound card.
.SH OPTIONS
Alsaconf accepts the following options:
.TP
.B \-l, \-\-legacy
Check only for legacy non-isapnp cards
.TP
.B \-m, \-\-modinfo
Read module descriptions instead of reading a card database.
.TP
.B \-s, \-\-sound\-wav\-file
Use the specified wav file as a test sound
.TP
.B \-u, \-\-uid uid
Set the uid for the ALSA devices (default = 0)
.TP
.B \-g, \-\-gid gid
Set the gid for the ALSA devices (default = 0)
.TP
.B \-d, \-\-devmode mode
Set the device mode for the ALSA devices (default = 0666)
.TP
.B \-r, \-\-strict
Set strict device mode (equiv. with -g 17 -d 0660)
.TP
.B \-L, \-\-log
Logging on /tmp/alsaconf.log
.TP
.B \-p, \-\-probe card-name
Probe a legacy non-isapnp card and print module options
.TP
.B \-h, \-\-help
Displays this help text
.SH DEBIAN SPECIFIC
In Debian, the default gid of the device files is 29 (corresponding to the
audio group) and the default device mode is 0660.
For the ALSA base package, see also
.I /usr/share/doc/alsa-base/
