Enter the two numbers you want to connect, separated by a space, then hit return. To see the list again, type 'l'. To disconnect clients type 'd' and then the two clients separated by a space Control-D will end the program here's what's connected to jack so far: 0) Jack: JackClient::SetupDriverSync driver sem in flush mode 1) Jack: JackFifo::ConnectAux name = /dev/shm/jack_fifo.1000_default_lsp 2) Jack: Already connected name = lsp 3) Jack: Clock source : system clock via clock_gettime 4) Jack: JackLibClient::Open name = lsp refnum = 4 5) system:capture_1 6) system:capture_2 7) system:playback_1 9) aqualung:out_L 8) system:playback_2 10) aqualung:out_R 9) aqualung:out_L 7) system:playback_1 10) aqualung:out_R 8) system:playback_2 11) Jack: jack_client_close 12) Jack: JackClient::Close ref = 4 13) Jack: JackClient::Deactivate 14) Jack: JackSocketClientChannel::Stop 15) Jack: JackPosixThread::Kill 16) Jack: JackClientSocket::Close 16) Jack: JackClientSocket::Close 18) Jack: JackFifo::Disconnect /dev/shm/jack_fifo.1000_default_lsp 19) Jack: JackLibClient::~JackLibClient 20) Jack: JackShmReadWritePtr1::~JackShmReadWritePtr1 4 21) Jack: Succeeded in unlocking 120 byte memory area Traceback (most recent call last): File "./jackctl20100526.py", line 27, in <module> get_list() File "./jackctl20100526.py", line 22, in get_list print " %s) %s" % (listp.index(i.lstrip()), i.lstrip()) ValueError: list.index(x): x not in list -- Regards, Philipp ----- "Wir stehen selbst enttäuscht und sehn betroffen / Den Vorhang zu und alle Fragen offen."
