MBP Input Select

**thxgoon** · **03-18-08, 08:50 PM**

Well I figured out why I was getting erroneous readings vs the old version. For some reason REW is choosing the built in mic over the line input. I have the settings in REW set to Default Input and the Audio MIDI panel default set to line in as well as the line in on the sound control panel selected. Still REW is only looking at the built in mic for input. Any ideas what else I might try? Thanks!

Are you running OS X 10.4? There is a bug with Apple's JRE under 10.4 that whatever input you select in System Preferences the input that is passed to Java applications is always the built-in device. That has been fixed in 10.5.

So is this a problem that there is no getting around? If so that's really a bummer. I wish Apple would get things together with Java...

I am using 10.4.11 and Java 5

I couldn't find any way around it, but maybe Apple will make Java 6 available for 10.4 and fix it that way.

Well I called Apple today and they claim the bug to be a 3rd party developer problem. I emailed Sun Java support so we'll see if they get back to me about it. I don't understand why they won't make Java 6 available for 10.4.

Sun doesn't provide the JRE for OS X, Apple do. Funny how the "3rd party developer problem" is cured in 10.5 with no action from the 3rd party developer

How can it be a 3rd party problem that asking Apple's JRE to return the default input always returns the built-in input under 10.4, but works as it should under 10.5?

From the Java for Mac OS 10.5 release note:

Radar #4985417

USB Microphones are not recognized as default input device.
Description:

Java Sound now returns the default input device as the first entry in an array specified by given selection criteria.

Resolution:

This problem is now fixed.
