Hi all,
This may not be exactly part of BLFS but still is related. Just trying my luck
in case someone on our lists have been playing with JACK. I have tried google
as well as man but have not found a remedy.
I want to use JACK with ardour-2.3.1. But it gives the following messages:
1. The output of the following command is given below:
[EMAIL PROTECTED]:~> jackd -v -R -d alsa -d hw:0 -r 44100 -p 1024 -n 2

2. The output without realtime option (-R) gives the following output:

3. Trying to start JACK with QJackCtl - which is an application for starting
the server- get the following error:
cannot load driver module alsa
no message buffer overruns
10:00:58.001 JACK was started with PID=15338.
10:00:58.002 JACK was stopped successfully.
10:00:58.003 Post-shutdown script...

jackd: no process killed
10:00:58.410 Post-shutdown script terminated with exit status=256.
10:01:00.114 Could not connect to JACK server as client. - Overall operation
failed. - Unable to connect to server. Please check the messages window for
more info.
JACK tmpdir identified as [/dev/shm]
4. On starting from ardour I get the following error:
Ardour could not start JACK
There are several possible reasons:
1)You requested audio parameters that are not supported..
2)JACK is running as another user.
Please consider the possibilities and perhaps try different parameters.
Can anyone suggest a solution please?
Thanks & Regards
