What adaptor do I need for HDMI and Audio from PC for best sound?

17 posts in this topic

I've got a Dell 24" monitor on my PC at home with HDMI input - no VGA or DVI - which also directs the sound output up to the monitor (as I would expect an HDMI connection to do).  The monitor has no speakers, but it has an audio jack out.

 

It's an OK idea, but the sound quality from running an audio jack lead into the Bose sound system makes for interference.  The Bose system plugs into the USB port on the PC, and there's no way of telling the PC to chuck the sound out via the USB port rather than via the HDMI (as far as I can find).

 

So what I need is some kind of adaptor which plugs into the HDMI output on the PC, then I can plug an HDMI cable from this box into the screen and hopefully the Bose USB cable into it as well - video output goes to the screen and audio output goes to the Bose box of tricks. Alternatively, in a worst case scenario, I can plug an audio jack cable from the adaptor into the Bose system - must be better quality than going all the way to the monitor and back out via an audio jack cable?

 

Does anyone have any ideas please?

I know its possible, as my old Xbox 360 came with a similar adapter that takes the hdmi for visual but also gives me an optical out for audio. Rather than go all through my receiver, the visual goes straight to TV, audio goes through receiver.

Cant say ive seen the same for your needs and just wondering whether its possible as the hdmi output is digital in my mind and you couldn't split off the sound to an analog input? I may be totally wrong here though. Does the Bose have an optical in? That would replicate my situation if so.

Does the PC not have an audio out jack?

You want as few connections as possible so direct from PC to Bose using whatever the PC's best audio output is.

Pc has an audio jack out, but the sound needs to go out via the Bose USB connection, not audio jack - i.e. trying to get as good quality sound as possible.

 

It just happens that the PC came with HDMI monitor output - damned modern hi-tech stuff :P

Not sure what USB sound quality is like to be honest, I'd be surprised if it was any better than a standard analog 3.5mm jack?

Not that that helps you much if it has to be a USB connection, does the computer not recognise the Bose as a speaker via it's USB connection? You've tried just plugging it in while it's turned on I'm sure?

USB sound will just be digital - quality will be driven by the quality of the DAC which will be terrible in a monitor.

 

You can change your outputs though? Not working for you? Sound in Control panel you can select multiple different sources.

 

Cheers Mac - I'll have a play tonight +++

Yes it does recognise it and Windows 8 picked up the correct drivers etc - just because the monitor is plugged into the HDMI port, the pooter is (correctly) channeling all the sound that way.

 

Not-wife wants her audio jack cable back for her car, so I need to figure something out :)

In which case as Mac says above, you should be able to direct the audio output in the sound settings, that's what I always do when using a USB speaker.

I don't know why anyone hasn't suggested the obvious solution.

 

Buy an iMac 27 and be done with it. :roflmao:

The easiest way I got something like this worked for me was to change the Default Sound Output Device to the output I wanted.

You need a HDMI audio extractor. I had the same issue when i need to extract the audio signal from the hdmi in order to process the sound through my av amp.

 

so you will have HDMI from PC to HDMI Audio Extractor input & then output to monitor and 2nd output via optical or 3.5mm jack to Bose

It needs usb connection to power it.

This is the one i used http://www.amazon.co.uk/gp/product/B00LPHJEAE?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

That doesn't give him the required USB output for the sound he needs.

Im sure there is a usb to 3.5mm converter available but not had  chance to look. Is there no other audio output from the bose?

3.5mm jack into the Bose, but that kinda defeats the object - if I can I want to use the sound going via the USB - still not tried to change the config of where the sound comes out of the PC though - hopefully have a look this weekend +++

Yeah you can get USB -> 3.5mm jack but they're cheap shit with rubbish DAC in them.
