Transcoding converts one format to another so that it plays on your TV. It is not relevant to the issue I mention with the audio.
The YouTube video plays its audio on the PC because the PC is running a web browser without actually you seeing it. That browser content is redirected to TV. When the audio content is not redirected in this fashion then it ends up playing on the PC.
With regard to the screen server performance, please note that a fast laptop is helpful but event core i3 is enough as long as you reduce the screen res to 1280x720, and disable Windows aero. Also an AMD CPU is not recommended because when H.264 encoding needs to happen hardware acceleration is only supported for Intel.
