Audacity 1.3.9 too slow in Karmic Koala

Post by attorianzo » Mon Nov 02, 2009 6:54 pm

I used to use Audacity with any trouble with Ubuntu Jaunty.
Now I have installed Ubuntu Karmic but I have found Audacity howfully slow.

Just for example, when I push the "stop" button while I am recording, it stops after 7 or 10 seconds.

The system seems to run quite good but audacity...

Is there any way to fix it?

Delete the audacity.cfg file from /home/username/.audacity_data
This will reset the Audacity Preferences and set it to the default settings.

Do you have "Pulse Audio Device Chooser" and "Pulse Audio Mixer" installed? If not, install them from Synaptic.

Open Audacity and right click on the recording meter and activate the recording meter.
Open Pulse Audio Mixer from the Device Chooser and go to the Recording Tab.
Set Audacity to record from your desired recording device (make sure that you choose a real device and not a "Monitor" device.

Record or generate some audio and hit play then pause.
Go back to the Pulse Audio mixer and check that Audacity is connected to the correct hardware.

If the Pulse Audio Mixer does not show your hardware correctly, then something may have crashed PulseAudio and it has not initialised correctly (for example Skype or Jack). If this happens, (make sure that Skype is not running), kill PulseAudio (Alt+f2 then type "killall pulseaudio" [without quotes]) then restart it (Alt+f2 then "pulseaudio").

It seems I fixed it simply setting "pulse" as output and input device as well..bah.

Thanx Steve.

It's still worth having "Pulse Audio Device Chooser" and "Pulse Audio Mixer" if they are not already installed. Apart from anything else it allows you to record "Stereo Mix".
Are these installed by default in Karmic? (PulseAudio recommend that they should be installed as part of any system that uses Pulse).

No, I think that only gnome-volume-control is installed by default in Karmic.

I installed by myself pavucontrol.

Somewhere I have read that padevchooser is almost deprecated..

Thanks for the update. You are correct, padevchooser is now obsolete and you should just use pavucontrol.
