# .asoundrc to use skype at the same time as other audio apps like xmms
#
# Successfully tested on an IBM x40 with i810_audio using Linux 2.6.15 and
# Debian unstable with skype 1.2.0.18-API. No sound daemons (asound, esd, etc.)
# running. However, YMMV.
#
# For background, see:

# https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1224
#
# Usage:
# 1. cp .asoundrc ~
#(DM)# 1. = Copy once this file into ~ as ~/.asoundrc
# 2. ALSA_OSS_PCM_DEVICE="skype" aoss /path/to/skype
#(DM)# 2. = Use this command to launch skype
#(DM)# Skype launches much faster with option --disable-dbus, thus
#(DM)# ALSA_OSS_PCM_DEVICE="skype" aoss skype --disable-dbus
