I provide 2 feeds and I use 2 sound cards on a single PC. as of late I have been getting complaints of low audio. It turns out that one feed is crossing into the other and it seems to be getting worse.


Has anyone had a problem like this and is the a fix?

OK It sounds like the driver or the audio decoder is not working correctly on the windows side or the encoders for the software is detecting both cards, have you check the settings for the encoders aka the software to stream the audio?

No I have not check the encoders. I have added a 3rd sound card and what ever combination I use, I get the same problem. I am going to eliminate the scancaster software and hook some speakers up and see if I get the same thing.


Stay tuned.

I turned off both instances of scannercast and connected speakers to each of the 3 sound cards. Through each set of speakers I can hear the input from the other sound cards. it is like the input is merging to all the outputs!


What is going on?

It could be a cable issue. Swap cables to see if the low audio moves to the other feed

The low audio is coming from the other sound card, but I swapped cables anyway. No Change.

Not really, Like I said I have run 2 feeds on this PC before and never noticed any cross talk between the sound cards before. It could have been doing and nobody complained, I don't know.

Does it matter if I use a stereo cable verses a mono cable?

It can degrade the sound and make tge sound from the scanner sound like a tin can or blank, scanners do have 1/8 pkugs that have outputs
For headphones and need dual channel outputs

Switch to USB sound cards with some isolation transformers and your problems should go away. I'm running 6 sound cards on my machine with no issues.
