The utility model relates to a sound circuit for a television provided with muting effect, comprising a sound volume control unit 1, a first muting circuit 2 and a second muting circuit 3. The first muting circuit 2 responds channel conversion signals or artificial set muting signals to control the sound volume control unit 1 to work normally or have no signal output; the second muting circuit 3 responds disconnect signals to control the sound volume control unit 1 to work normally or have no signal output. The sound circuit can obtain muting when the television set changes channel, automatically selects channel, stores channel and switches TV/AV; or the sound circuit can obtain muting in any condition under setting; when the television is turned down, the sound circuit can avoid accompanying sound impacting.
