Try closing Media Server in MC19, as well. But the problem may be at the driver level. You could run one with DirectSound.
MC19 can also act as an ASIO driver. See the New Features list for information on that. But that's probably separate from your problem.
How can I close Media Server function in MC19? Tools-Option- General-some where??
I now understand that MC18 ASIO setting is trying to use MC19's JriverAsioDriver.dll because MC19 itself behaves as an ASIO driver to any other software including MC18 which would use ASIO mode. In this case, however, MC18 should properly call and enable playback in ASIO mode using MC19's JriverAsioDriver.dll, but actually it causes fatal error to completely freeze MC18. At this time, I would not like to use "MC19 as ASIO driver" with the stable MC18; MC18 should act exactly identical to MC18 before MC19 installation. Together with stable MC18, I am jsut testing MC19.
We need to know proper procedure(s) for MC18 to run as it was before installing MC19! Otherwise, this problem may happen with other audio softwares in ASIO mode.
I agree and support that "MC19 can also act as an ASIO driver", but we need a simple and easy way to disable the feature.
