jackd does not work, cannot configure SBLive for audio recording in SuSE 9.0
 

I am new to Linux, and I'm trying to configure my sound card so I can record from mic/line in on my SBLive to Rosegarden or Audacity, which requires JACK to be setup. When I run "jackd -d alsa -d hw:0" as the SuSE manual states, I get the following output:

the capture device "hw:0" is already in use. Please stop the application using it and run JACK again

I have no programs running that are using the soundcard. I am only using the shell in KDE. I even tried it in failsafe mode, and I got the same result. How can I find out what is making it busy and disable it so I can run jackd?

Thanks for any help you can provide.

Hi.

My set up is similar to yours (SBLive, SuSE using KDE), so when I tried the command you mentioned and it worked just fine, I got a sneaky suspicion. I went to the Sound System configuration in the Control Center, turned on "Enable networked sound" and tried it again - this time I got the exact same error you did.

So, if you'd like to give this a try, open the Control Center, choose "Sound and Multimedia" then "Sound System" (or something close). If you see that networked sound is enabled, disable it, click okay and try the jackd command again.

Good luck.

Thanks a lot! I disabled network transparency, and jackd is now running properly (I think). But is it supposed to take forever? I ran it in verbose mode, and after the initial starting message, it keeps spitting out stuff like:

load = 0.0495 max usecs: 46.000, spare = 46393.000
load = 0.0420 max usecs: 16.000, spare = 46423.000
load = 0.0425 max usecs: 20.000, spare = 46419.000
load = 0.0460 max usecs: 23.000, spare = 46416.000
load = 0.0553 max usecs: 30.000, spare = 46409.000
load = 0.0503 max usecs: 21.000, spare = 46418.000
load = 0.0467 max usecs: 20.000, spare = 46419.000
load = 0.0470 max usecs: 22.000, spare = 46417.000
load = 0.0461 max usecs: 21.000, spare = 46418.000
load = 0.0521 max usecs: 27.000, spare = 46412.000
...ad infinitum

Rosegarden never hooks up with Jack (in verbose mode its supposed to tell you when it does), and I can't run Audacity at all (before it ran, but would not record properly). What am I doing wrong? Thanks for any help.
