Solved! How do i connect my Sony DAV-TZ145 to pc?

Solution
Your only option with that Sony is to use the analog stereo output of the PC to the aux analog stereo input on the Sony. Select a surround sound mode that works for stereo inputs such as Dolby Prologic. The USB connection is only for a drive and the Sony doesn't support HDMI-ARC.
