A few days ago my Sound Blaster Live 24bit external audo box stopped responding to JRiver. It responds to Tests from the Windows Control Panel so I feel that JRiver is no longer controlling it properly. I don't recall doing anything to the settings and have tinkered with them to no avail. It shows up in the list with the other sounds devices. I select Left Front + Right Front for my Master Bedroom zone, Direct Sound, no DSP filtering, and that's how it has always worked. Just stopped about 3 days ago. My kitchen zone is setup to use Left Rear + Right Rear and it also is no longer working. I have other zones that use different sound cards and everything else is still working. I test with headphones plugged directly into the soundblaster.
It seems to me jriver is no longer communicating with the device since tests from the Windows 7 control panel output test sounds successfully.
What is the best way to troubleshoot this problem. I reinstalled the creative drivers which were initially there. Windows is not setup to update itself. Did JRiver update itself and break something a few days ago? Current version is 17.0.165
Thanks for any suggestions.
