5 sound regression tests fail on Windows

JDK            : JDK1.5.0-b17, JDK1.5.0-b16 (passes using JDK1.5.0-b14, JDK1.4.2-b28)
Testbase       : Regression-test
Platform[s]    : Windows
switch/Mode    : default
Falling test[s]: 
        javax/sound/sampled/Controls/ReverbControl/SimpleMidiPlayer.java 
        javax/sound/midi/Sequencer/TickLength.java
        javax/sound/midi/Soundbanks/ExtraCharInSoundbank.java
        javax/sound/sampled/Clip/Duration/ClipDuration.java
	javax/sound/midi/Sequencer/MidiCrash.java 
	
These tests fail on Windows platforms only if a sound device is not available. 
But there are multimedia drivers which are installed in Windows by default 
(for example: Audio Codec, Legacy Audio Drivers, Media Control Devices)
Therefore the method "public static boolean isSoundcardInstalled()" works incorrect in these tests.

	Easy fix of the reg tests only.


 xxxxx@xxxxx  2003-10-12
	On Windows, the function isSoundCardInstalled still reports devices, even if no devices are installed, due to bug 4936397. The "other" devices, like codecs, should not appear in Java Sound's list of mixers.

	Since the implementation should now always return 0 mixers if no sound hardware is installed, the implementation of isSoundCardInstalled can be made much simpler, by e.g. calling AudioSystem.getTargetDataLine.
