+NAME
+ossdetect - Open Sound System audio device detection program.
+
+SYNOPSIS
+ossdetect [-diuv] [-m<mode>] [-L<path>]
+
+DESCRIPTION
+The ossdetect application performs automatic detection of soundcards.
+The application looks at the /usr/lib/oss/etc/device.list and performs
+automatic detection. It will create a file with the list of the configured
+drivers in /usr/lib/oss/etc/installed_drivers.
+
+The Input Multiplexer driver (IMUX) is not configured by default and
+can be added to the OSS configuration using the -i option.
+
+OPTIONS
+-d Create device file links.
+-i Adds the oss_imux driver.
+-m<mode> Create nodes with permissions set to octal <mode>.
+-u Adds the oss_userdev driver.
+-v Verbose output.
+-L<path> Use <path> as root directory for OSS files.
+ Default: Path from /etc/oss.conf, followed by /usr/lib/oss.
