Re: HP ProDesk 405 G2 MT
According to the specs it has VGA and DispayPort video outputs... So 2 choices..
1) If your TV has an audio input (most do), get a 2.5mm to 2.5mm audio cable, and plug it into the speaker output from your computer to the TV's audio input. Set that as the default sound output from your computer. You'll have to use this method if you're using the VGA connection on the computer.
2) You could use the DisplayPort output on the computer and get a DisplayPort to HDMI passive adapter, which should then transmit the audio as HDMI does through the single cable.
