Audio Streams

If a media file contains multiple audio streams, you can cycle through them all and select each one in turn

[F6] will cycle to and select the next available audio stream
the end of the cycle includes "Audio: no" which will mute the audio
pressing [F6] again will cycle to and select the first audio stream
meta-data details of each track will be shown in the Notification Area
e.g. Audio: (1) (eng Vorbis 6ch 48000 Hz) [default]

If you are listening through an external device (e.g. via a Bluetooth transmitter to your earphones) the audio can lag behind the video images

you can bring the audio forward in steps of 0.01 using Ctrl-[\]
repeat this until the audio is in sync with the video
if you bring the audio forward too much so that it is now ahead of the video you can delay it using Ctrl-[/], again in steps of 0.01
