Question Balance 'bleed' into other speaker

[jsedit]

I'm going mad trying to sort this out. I have a MONO audio track, playing out of the left channel only in Resolve (or any other program) - but something in Windows is bleeding the audio into the right channel. You can see in this YouTube clip Audio Test. The right meter is the Resolve timeline. The left meter is the Windows output. (I grabbed any mono clip, don't judge it!)

I've been into the SOUNDS setting, and checked the balance. If I turn the right one to 0, then sure, it doesn't play anything anymore. But once I turn it up, the sound comes back - even though clearly, nothing is being sent out from Resolve to the right channel.

Audio enhancements are off.

I've re-installed the motherboard audio drivers (Recon3Di) and it does the same through HDMI out as well as headphones / Line-out. It's not a speaker issue, it's something in Windows before it gets sent out of the system.

Anyone experienced this before, and know what I can do?

Windows 10 if that helps?

Not sure about the details of your current audio connections. However, you may not be able to achieve just one channel "output".

What audio cables are you using?

Mono, stereo? Microphone connections?

Are you able to provide a simple sketch or physical description of your audio setup?

Not sure if it’s related but I know that high end audio equipment has each channel going through a different amp chip. Cheaper equipment with both channels going through a single amp chip will suffer some level of crosstalk.

Hi Ralston, thanks for replying. Well, like I say - it's within windows, rather than it being a cabling issue. However, here are all the different ways I've tried outputting, in case I'm assuming poorly.

1. Headphones in the front of the case - audio bleeds
2. Line out from the Motherboard soundcard (Soundblaster Recon3D1 on a Gigabyte Z170X 7) using a stereo jack to two unbalanced XLR's into my Yamaha HS7 active speakes. - audio bleeds
3. SPDIF from the Recon3Di to a digital to analogue convertor - then into the HS7's - bleed.
4. DisplayPort to computer monitor - then switch audio to go to that monitor, and plug headphones into that - bleed.
5. Take the SDI output from my Decklink 4K video card into an SDI to HDMI convertor - plug HDMI into a monitor - and output audio from that - connect headphones and then Yamaha's - bleed
6. Same as above, but use balanced TRS jacks to Balanced XLR inputs on the Yamaha HS7 speakers - bleed.
7. Use a USB audio card - connect headphones and then Yamaha's - bleed.

And this happens for all audio out of the PC. Resolve, YouTube, HGS, Audacity - anything I play audio from isn't coming out true LR stereo. If I export a WAV file, and check it - it's proper stereo - it's just somewhere when it comes to audio monitoring, it goes kaka.

But like I say, the mix happens within the Windows environment. It's not the cable and the speakers that are mixing it - you can see that in the video I posted. Somewhere there's a setting that instead of being 100% left / 100% right for panning, it's like 80% 80% LR and 20%20% RL to have that little overlap bleed.

I'm stuck!

Moving your post and responses over to Home Audio.

Hopefully someone there will be able to identify the problem and suggest/provide a solution.
