- A Vivo LTV42FHDN 42” Full HD TV (2x HDMI inputs, 1x RCA stereo audio output, few other audio and video input connectors, and a set of really crappy built-in speakers)
- A Logitech 2.1 Speaker system connected to TV's RCA audio output
- An old DELL XPS M1330 notebook running Windows 7 hooked up to the TV via one HDMI port
- A new Chromecast I’m trying to setup connected to the other HDMI port.
When I watch TV and switch to the HDMI input of the PC I get audio through both the TV’s crappy built in speakers as well as the much better sounding Logitech Speakers. However, when I switch to the Chromecast I only hear audio through TV’s built-in speakers. I have connected other PCs and tablets through HDMI before and from what I recall, sound always came out external speakers.
Is there any reason for the PC and Chromecast to behave differently when connected via HDMI ? I tried both HDMI ports, went through TV's audio settings (which only has very few settings like bass, treble, and some sound profiles), but couldn't get the chromecast to output audio through external speakers.
Does this mean Chromecast doesn’t support somesort of an HDMI specification/standard my old PC does, therefore the TV can't split and reroute the audio ? Is there any way to get around this without buying new hardware ? Other than audio, rest of it works great ! For me spending $50 or so extra on additional hardware really defeats the purpose of buying a Chromecast, because for that price I could've bought a DLNA enabled media player.
Any help appreciated. Thanks.
