LinuxSecurity.com: Some issues relating to thread cancellation have been discovered in the pulseaudio package shipped with Mandriva Linux 2009.0. These issues could result in the crash of an application acting as a pulseaudio client. This condition is greatly exacerbated when the client is unable to connect to the pulseaudio server. Due to the fact that libcanberra is used to play event sounds in GTK apps, this problem could present itself when running GTK applications as root which, under some circumstances, was unable to connect to the user's pulseaudio daemon.

SYNOPSIS
paplay [options] FILE

DESCRIPTION

sndfile.
OPTIONS -h | --help
Show help.
--version
Show version information.
-v | --verbose
Enable verbose operation. Dumps the current playback time to STDERR during playback.
-s | --server=SERVER

--stream-name=NAME

--volume=VOLUME
Specify the initial playback volume to use. Choose a value between 0 (silent) and 65536 (100% volume).
--channel-map=CHANNELMAP
Explicitly choose a channel map when playing back this stream. The argument should be a comma separated list of channel names:
front-left, front-right, mono, front-center, rear-left, rear-right, rear-center, lfe, front-left-of-center, front-right-of-center,
side-left, side-right, top-center, top-front-center, top-front-left, top-front-right, top-rear-left, top-rear-right, top-rear-cen-
ter, or any of the 32 auxiliary channel names aux0 to aux31.
LIMITATIONS
Due to a limitation in libsndfile paplay currently does not always set the correct channel mapping for playback of multichannel (i.e. sur-
round) audio files, even if the channel mapping information is available in the audio file.
