I’m facing this issue since fresh install off ubuntu. My mic work well everywhere (and headphones, speakers too), but not on audacity. (picrel) http://i.imgur.com/xQTgkA8.png
And devices list…
Default recording device number: -1
Default playback device number: -1
No devices found
My audacity version is 2.1.2. It will be good if this can be fixed.
Have you installed PulseAudio Volume Control (pavucontrol)? Sometimes that helps.
Is some application or service taking exclusive control of the built-in sound card? If so then PulseAudio won’t get access and Audacity won’t see any devices through ALSA either.
Did you connect the USB mic before launching Audacity? Otherwise you have to use Transport > Rescan Audio Devices.
Nothing changed… It gives me error when i want to record
Error while opening sound device. Please check the recording device settings and the project sample rate.
You must connect the mic before launching Audacity, as we said.
Where did Audacity 2.1.2 come from?
Is this Ubuntu Studio?
This is only likely to be two problems - some other application or service has exclusive ownership of the audio device, as already stated, or there is some permission problem. It does not sound like a permission problem if other applications can use the sound device. Try shutting down those applications that can access the device.
Is pulse in the audio group? Type this in a terminal and hit ENTER on your computer keyboard:
You did not tell us where you got Audacity from. If you built it yourself you may not have built it correctly.
I would shut down all other applications that are using your sound card. Open System Monitor and shut down any audio daemons that may be running. Then Audacity should be able to use the sound card.
Or backup your data to a USB drive or similar and reinstall Ubuntu into a fresh partition on your computer. You said it was a fresh installation, but I can tell you that a few people have had messed up audio in 16.04 when they upgraded directly over a previous Ubuntu version. Ubuntu no longer recommend overwrite installations.
@gale I SAID it’s pure installation. Again, after shutting all apps that might using audio nothing changed. Should i reinstall it? I’m using apt package manager to install it.
Also I’m using cinnamon 3.0.
Theres a warning
(audacity:16023): IBUS-WARNING **: Unable to connect to ibus: Could not connect: Connection refused
It’s up to you if you reinstall Audacity. I doubt it will make any difference, from your description. “Something” is preventing Audacity accessing any devices so you need to find what that something is.
If you do reinstall the 2.1.2 package supplied by Ubuntu, first delete the ~/.audacity-data/ folder so that the new installation has clean settings.
You may be better asking on the Ubuntu forums. There is a reason Audacity sees no devices. There may be a sound daemon we don’t know about which you enabled by accident.
I found this old thread when trying to find solution to my problem which seems to be the same as
“dracconi”;s. All the details are the same on my set up too.
Is there any further info in this matter?
