problems with M-Audio Audiophile 2496 and Jack

Installation & Configuration Linux
#1

I recently purchased an M-Audio Audiophile 2496 to record my keyboard playing. Before, I used the onboard via chip which did its job. With the onboard card I was able to run jack+ardour and amarok/firefox+“a youtube video” simultaneously without any problems. But no with the maudio I have the problem that Jack always tells me that the device is already in use. See:

I haven’t found any other advice than to kill all apps which could use the device, which works but is a weak workaround. Cause I usually fire up ardour, checkout some music on youtube, and let the music inspire me. If something good came out I just click record in ardour and that’s it.

But now I always have to shutdown everything, start jack+ardour, shutdown everything, start firefox… I spent some time searching in various forums, docs, howto’s,… but haven’t came across a solution.

Hope you guys can help me out.

hi,

which distro, which version ?

is not pulseaudio running ?
$ ps -ef|grep pulseaudio ?

#4

Sorry, forgot to add my system specs yesterday. I’m on Kubuntu 9.04. The command from above leads to this output:

silentcry@silentcry:~$ ps -ef|grep pulseaudio
1000 4724 3803 0 22:02 pts/3 00:00:00 grep pulseaudio

I’m pretty sure that pulseaudio is not running (can’t kill such a process), but that line confuses me a bit (linux newbie here :slight_smile: )

#5

pulse does not seems to be up
try to change your default sound device in kde sound settings.

what’s teh ouput of ps -e ?

#6

you can see which program is using your sound devices with this command:

lsof /dev/snd/*

I think lsof means: list open files. It is a very powerful command with lots of other uses.

the pcm (playback and capture) devices are named like this: pcmC0D0p

C0: first sound card (counting from zero)
D0: first device
p: playback device (audio output)
c: capture device (audio input)
