Hi experts: I installed JACK and the GUI of it looks good. But it seems it will block the "audio application" and "audio application" will also blcok it. That is to say: 1) If I started the JACK by: sudo /usr/bin/jackd -r -m -dalsa -dhw:0 -r44100 -p1024 -n2 -P Then I open my web brower and try to play a streaming song(play by flash), the song can't play!
2) If I stoped the JACK Then I open my web brower and try to play a streaming song, the song played good!
3)if I play a song by mplayer or web brower at first Then I try to start the JACK, there is an error:
Acquire audio card Audio0 creating alsa driver ... hw:0|-|1024|2|44100|0|0|nomon|swmeter|-|32bit Using ALSA driver HDA-Intel running on card 0 - HDA NVidia at 0xfe024000 irq 23 the playback device "hw:0" is already in use. Please stop the application using it and run JACK again Cannot initialize driver JackServer::Open() failed with -1 Failed to start server
My system is Debian Lenny.
So how can I play sound with JACK started?
