how to get 5 channel stereo in Harman Kardon AVR 151

[vimals73]

My TV output is connected to Harman Kardon AVR 151. However, the audio is coming only in 2 channel stereo and not in 5 channel. How to change the settings.

You don't mention how the AVR is connected to the TV.
If it's connected by HDMI-ARC or optical cable then make sure you have the output in the TV set to bitstream 5.1
Then select Auto or Dolby as your surround sound mode.
If it's connected with an analog stereo connection then you need to select a surround mode for a stereo input. There are usually more than one. If the receiver is left on Dolby it will usually go to Dolby Prologic II automatically when it receives 2 channel inputs. The owners manual usually explains how each mode works.

Not all content will have rear information. A lot of programming will be center channel only unless you select a mode for a mono source.
