... For what it's worth, nowhere did you guys indicate this was a rare issue. A couple of forum members indicated they had a problem and you responded with what seems like "please go do my troubleshooting for me". Although this problem exists in Jukebox as well, all of us paid for Media Center and your attitude was similar to what I expect for support for free software.
Oh, I see. Maybe it wasn't obvious that those who posted in this thread and tried to help didn't experience the problems themselves.
If the JRiver developers could have reproduced the noise problem they would have immediately said something like "OK, we see it now. Please try the next build to see if our fix works."
If the users like me and others who posted in this thread would have experienced something as serious as totally broken audio playback after installing a new build the release thread would have been full of reports and the build would have been pulled by JRiver.
Now, back to the topic...
Sorry I missed that reply in the replies about the output mode/disk writer plug-in. I don't have anything fancy, no plug-ins, some DSP, nothing. Just MediaCenter. I'm seeing the noise issue, and yes, my motherboard uses an onboard nForce audio. I'm running XP (was SP2, but now just reformatted with SP3).
None of my PCs have an onboard nForce, so maybe the problem really is related to that sound device.
For now, I can only ask further questions:
Did you try to change the playback mode inside MC?
Does the sound device's control panel offer any options that you could try?
some DSP
Do you mean you have some DSP features enabled in MC's DSP studio? If yes, could you disable them (as a test)?
