Jack2 Issue - 2nd Part

Hi guys,
 i'm trying the latest version of Jack 1.9.2. The server starts normally:

20:13:58.608 JACK is starting...

20:13:58.609 /usr/local/bin/jackd -R -P89 -t1000 -m -dalsa -r44100 -p128 -n3 -D -Chw:0,1 -Phw:0,0 -Xseq -H -M

JackAudioDriver::ProcessAsync: read error, skip cycle

20:14:00.668 Statistics reset.

20:14:00.689 Client activated.

20:14:00.727 JACK connection change.

But when i use it with other programs (vsthost, lv2rack, jackrack, qsynth...), i get xrun like this:

JackEngine::XRun: client = Wine_ASIO_Jack_Client was not run: state = 2

JackAudioDriver::ProcessAsync Process error

20:18:15.852 XRUN callback (1).

Is it a known problem? It depends on hardware or software i'm using? Bad installation?

Thanks as always!

Marco
