Hard to find specs on that TV so don't know what kind of audio outs it has but it seems to support ARC over HDMI so make sure the HTS has ARC too.
If it has an optical audio out that would be another choice for connecting an HTS.
Last choice would be analog stereo. If the TV has optical only you would need a DAC to convert to analog http/wholesale.parts-express.com/parts-express-dac-digital-to-analog-converter-%2851-compatible%29--180-999
