ubuntu 9.04 audacity 1.3.7 recording just stops

[chetvolpe]

Running ubuntu 9.04 on a 1GHz AMD 32 bit processor and Audacity 1.3.7. Recording via USB from an Ion turntable and at random points in the recording process (anywhere from 3 to 20 minutes) CPU goes to 100 % and Audacity just stops recording. Monitoring the playback from the turntable and it continues to play. I am including the log file info at the time of the failure. I have attached a screen shot and results of lshw are available if needed. While it works, it works well... Any help would be much appreciated - Chet

Sorry about the double append of the screenshot above... see http://ubuntuforums.org/showthread.php? ... ost7338941 where I was able to also post the lshw output.

Anything on this? I'm getting exactly the same thing. I'm also using Ubuntu 9.04 with Audacity 1.3.7 on a eeepc 900. I wasn't using Audacity on the machine before this, so I have no previous reference. The only thing different for me is that my CPU doesn't always go to 100%. Sometimes it does which stops the recording, but other times it just stops.

The time it stops is random. The quickest it stopped is 5 seconds, but the longest it has recorded is a minute, forty three seconds.

It's not frozen, just simply stops recording. I can hit stop and go back and listen and everything seems fine.

There is plenty of disk space, and ram is barely being touched. I upped the priority of the process to -20, but this didn't change anything.

Now I just tested Audacity on my tower computer [also running Ubuntu 9.04 and Audacity 1.3.7], and it is running at 100% CPU (no fault of Audacity, its been running Mozilla and Tweetdeck too long), but this isn't affecting Audacity, so far. In fact, I just ran recorded for over a half hour with zero issues. So now I'm really lost. It works great on one computer, and stops randomly on the other computer Of course it stops on the laptop, which is what I need to record on.

Ubuntu 9.04 uses Pulse audio by default, and this can be a pain for setting up recording. After upgrading from Ubuntu 8.10 to 9.04 it took me a couple of hours to figure out how to configure the sound system so that I could record with Audacity - now that I have it set up I don't really want to mess with it, but if I were doing this again I think that I would try by removing pulseaudio completely.

Another option is to use Audacity with Jackd. This works nicely on my machine, but it has the old problem of no ports in Jack Connect unless Audacity is in record or playback mode. It does however connect automatically to "system" in and out when required.

Well, that fixed it... got rid of Pulse Audio and installed esound... thanks to stevethefiddle and the post at http://www.ubuntugeek.com/fix-for-all-p ... ssues.html.
