+.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/
