Stereo Trouble, Software or Hardware?

[Adenosine]

Not sure if this is a hardware issue or a software one. First I’m running an I5 system with onboard audio and a Rocketfish 5.1 soundcard for my stereo feed. I’m using ProScan for my software. I use the onboard audio for recording and everything else.

The problem is my left and right channels switch in my feed intermittently. I believe it’s when my system reboots from the scratch. The fix seems to be restarting ProScan and the Left is Left and the Right is Right.

Couple of things are odd, It wasn’t doing this for the first few months of the feed, now just started out of the blue. The other odd thing is I think Audacity might recreate the flip. None of these things I can make happen when I want them too.

Any ideas?

This seams to be a ProScan issue with stereo streaming. All I have to do to fix the stream is restart ProScan. The stream can be up for hours without an issue before the audio switches or it can go a week.

Where do the channels cross? Next time it happens, Would you do the following test.
1) Monitor the audio thru the computer speakes while moving the Windows mixer(mic or line input) left & right controls without ProScan involved. Are they crossed?
2) View the ProScan level indicators while moving the Windows mixer(mic or line input) left & right controls. Are they crossed?

The feed flipped again last night. Since the stereo feed is on my second sound card I can’t check with speakers, however, my darkwood meter was showing the input had flipped as did the audio input on the ProScan. When I restart the ProScan the Audio input goes back to being correct. The Darkwood Peak Meter was still showing the incoming flipped. Cheap sound card?

The feed is through the Line input on the 5.1 sound card.

This is about the strangest thing i've seen. I'm at a lost to explain it.

Did anything change on your machine? New software?

What happens if you restart the Darkwood Peak Meter?
Is there a later version of the sound card driver available?
Are the inputs set to the same on the Darkwood Peak Meter and ProScan?
Next time it happens, instead of restarting ProScan, change the input from Primary Sound Capture Device" to "Analog Mix" or visa-versa.
