Hello everyone,

To my surprise, jackd could not start this morning (using
qjackctl).

User name was added to the audio group. The audio devices are:

% cat /proc/asound/cards

0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7d10000 irq 53

1 [M1010LT ]: ICE1712 - M Audio Delta 1010LT
M Audio Delta 1010LT at 0xd040, irq 18

Interface in qjackctl is specified as 'hw:M1010LT'

Here's what happened:

Sun Mar 31 07:37:23 2013: JACK server starting in realtime mode
with priority 10

Cannot connect to server socket err = No such file or directory

Cannot connect to server request channel

jack server is not running or cannot be started

Sun Mar 31 07:37:23 2013: ERROR: Failed to acquire
device name : Audio1 error : Method "RequestRelease" with
signature "i" on interface "org.freedesktop.ReserveDevice1"
doesn't exist

Sun Mar 31 07:37:23 2013: ERROR: Audio device
hw:M1010LT cannot be acquired...

Sun Mar 31 07:37:23 2013: ERROR: Cannot initialize

Sun Mar 31 07:37:23 2013: ERROR: JackServer::Open
failed with -1

Sun Mar 31 07:37:24 2013: ERROR: Failed to open
server

So I tried with 'hw:1' from the drop-down menu:

Sun Mar 31 07:34:57 2013: control device hw:1

Sun Mar 31 07:34:57 2013: ERROR: Failed to acquire

doesn't exist

Sun Mar 31 07:34:57 2013: ERROR: Audio device hw:1
cannot be acquired...

Sun Mar 31 07:34:57 2013: ERROR: Cannot initialize driver

Sun Mar 31 07:34:57 2013: ERROR: JackServer::Open failed with
-1

Sun Mar 31 07:34:57 2013: ERROR: Failed to open server

What could be the cause of this problem ? - thanks !
