Value Description
devices such as, digital telephone systems.
Most digital signals (HDMI orSDIsources) use 48 kHz audio. Matching the encoded
level with the source level provides the best sound quality by avoiding audio
resampling. For analog signals, 44 kHz provides higher sampling.

value you'll need to use a media player (or install ASF browser plugins)
to preview your channel.
