# This fixes the pulseaudio profiles of the Thinkpad T490.
# The laptop contains a single audio card with 5 sub-devices. Default pulseaudio only offers a single sink
# which can only be switched between speaker/HDMI via a manual profile change.
# This configures a profile set for pulseaudio which offers multiple sinks corresponding to the
# speaker + 4 HDMI ports. This allows the user to play audio streams on the speaker and any of the 4 HDMI/USB-C
# ports at the same time.
