Re: qjackctl issues

I would think the error message is pretty self explanatory. Hint: 'cannot' normally means something went wrong. Also, Google is your friend.

Re: qjackctl issues

but anyways.... im not wanting to run it as root.
if anybody knows exactly how to get around these original errors, i would love to hear your thoughts....
cannot create /dev/shm/jack-1000 directory (Permission denied)
cannot create server sockets
cannot create engine

Only thing i found on google was this http://en.gentoo-wiki.zugaina.org/index.php/JACK
But I don't even have a /var/run/jack to add permissions to normal user.... I only have these in that directory;

ConsoleKit  daemons   dhcpcd-eth2.pid  network        syslog-ng.pid
PolicyKit   dbus      hald             pm-utils       utmp
console     dbus.pid  hald.pid         sudo           xauth
crond.pid   dhcpcd    kdm.pid          syslog-ng.ctl  xdmctl

Re: qjackctl issues

/dev/shm isn't a 'directory to create'. It needs to be mounted tmpfs. The default /etc/fstab should do this.

Re: qjackctl issues

As root make the /dev/shm/ directory.

mkdir /dev/shm/

Then put this in your fstab >>>

none                   /dev/shm      tmpfs     defaults            0      0

reboot
Should work now.

Also I found this pdf 'KNOWING JACK' very helpful >>>

Re: qjackctl issues

That's in the stock fstab already But yes, do ensure you have it.

Re: qjackctl issues

Maybe this line

shmfs                  /dev/shm      shm       defaults            0      0

Re: qjackctl issues

Heh, it's the same. tmpfs was shmfs

If after everything it still doesn't work, I see a deeper issue.

Re: qjackctl issues

oops... i forgot about this Post i created.... LOL.
Thanx for the replies Folks!

I actually fixed it buy installing "phonon-xine"
Because my HDA Nvidia sound device was not working properly when booting into my desktop... qjackctl kept complaining it was in use.......

for some reason the Gstreamer backend seems buggy...... but xine works perfect for me, and now Everything else is working fine with qjackctl...........
