Alternative Alsa device in Mplayer

In general, pulseaudio manages my sound cards, but sometimes I want to play a video in mplayer while playing music in mpd, but on different devices.

To discover the available cards:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC269 Analog [ALC269 Analog]

card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]

To change the device, just play the video using the -ao parameter as in the example:

• Sound through headphones: mplayer Koyaanisqatsi (1982).mkv -ao alsa:device=hw=0.0
• Sound through the TV: mplayer Koyaanisqatsi (1982).mkv -ao alsa:device=hw=0.3
