I have a Samsung smart TV with the following options:

  • HDMI with ARC
  • Digital Optical Audio
  • and 2 Channel 3.5 mm

I picked up some philips sw3440/37 speakers but it has an old VGA db15 style connector.

I've been looking for the simplest way to connect them and if possible still get 5.1 audio. Ideally something like HDMI ARC to audio vga, and a cheap solution. Most of the HDMI->VGA adaptors I've found are non audio or only 2 channel, I'm not sure these would work.

Does anyone have any products or ideas? If necessary I can modify the philips to go from db25 to standard set of RCA plugs. Here is the VGA pin-out for audio, but I don't know if this is some special Philips thing or not:

After looking into it further this Philips device use of VGA is non-standard and there really doesn't seem any good way to interface with it. I would need something with all the 5.1 analog outputs, then hard wire them to the VGA connector. I think for now, I'll try 3.5mm 2 channel and see how that works, then go from there. But I'd be interested in any suggestions as types of simple hardware adapters to go from the TV to the analog 5.1 audio channels.


I got it working using a VGA breakout but the sw3440 had a damaged speaker and the amp kept getting quite hot, so I had to abandon it. Thanks for the help though.

    Digital audio out to a 5.1 decoder in your sound system. – keshlam Nov 16 '15 at 0:09
  • That sounds like a solution @keshlam. This might be one of the few instances I might include a product that might make sense. I see a lot of stereo receivers with several HDMI Inputs, that I'd assume do good job decoding. I'm shopping for one myself right now actually. – BrownRedHawk Nov 16 '15 at 13:05
  • Also, some receivers can take a simple digital coax or optical input even if they saen't wired in as video switchers. – keshlam Nov 16 '15 at 15:58
  • do you only have the speakers/subwoofer, or do you also have the DVD player that goes with it? – longneck Dec 1 '15 at 15:31

I don't think you're going to get very far with this.

For one thing are you certain the TV has audio outputs not inputs? Whole thing is dead if not. Even if they are 5+1 outputs, which I doubt - no way - they'd have to be amplified outputs to drive the speakers. That's not going to be the case.

The way the Philips system was supposed to work, you went from a DVD player to the subwoofer with the db15 cable, then the signal split out from the subwoofer to the speakers. I think the subwoofer amplified the signal. So without the subwoofer, you're stuck.

You could make an adapter to run the subwoofer off a home theater receiver, and you could run the other speakers directly to the speaker. Should work.

  • Actually the TV has all these audio outputs and the sw3440 has the analog inputs (including amplifiers and sub woofer). I was able to directly wire them up however the amplifier was overheating and one of the speakers was blown, so I gave up on it. – user6972 Jan 29 '16 at 18:34
