Description

Name: rlT66838			Date: 03/09/2000


java version "1.3.0rc1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0rc1-T)
Java HotSpot(TM) Client VM (build 1.3.0rc1-S, mixed mode)

When playing back using a SourceDataLine, I cannot start recording using a
TargetDataLine. My code works for both recording and playback, but not at the
same time.

The exception that occurs when requesting a TargetdataLine is that the format
does not match the format of an already open line. In my code only bigEndian of
the 2 lines is different. The same code (except JS0.99 API modifications)
worked well with JDK1.3beta for recording and playback simultaneously.

EVALUATION ###@###.### 2002-11-02 Java Sound in J2SE 1.4.1 and before requires the same playback format as for recording. To get best results, first open the recording TargetDataLine and then the SourceDataLine. This limitation should not exist with 1.4.2 anymore. Furthermore, the direct audio renderers that are planned for tiger should remove this problem. When using the ALSA mixer in 1.4.2, full duplex should be possible, too, unless the soundcard does not support full duplex. ###@###.### 2003-09-26 Fixed with availability of DirectAudio drivers on all platforms.
