I can record from line-in after configuring my soundcard for input. That works fine.
However, when I play internet radio via Rythmbox, how can I get the sounds I hear into Audacity?
I tried the recording device menu, without success.
Thanks for any help,
ulrich
To record sounds that are playing on your computer, see in the manual here: http://manual.audacityteam.org/o/man/tutorial_recording_computer_playback_on_linux.html
To record sounds that are playing on your computer, see in the manual here: > Audacity Manual > … linux.html
I tried to follow the advice there, but there are two (possibly related) propblems:
When I click the recording device button in audacity, I see a list of devices, seemingly all microphones, NOT just pulse.
When I start pavucontrol, I see under “Recording” just the line “GNOME Volume Control Dialog” and cannot switch to “Monitor of CM 106 Like Sound Device Analog Surround 5.1”,
which is the current output device.
I try to attach two screenshots.
I presume that you have some version of Ubuntu? Which version?
Does your computer have an internal sound card? If so, it does not appear to be listed in the recording devices, which is strange.
Please try rebooting your computer, then (without opening any other programs), launch Audacity and select “Help menu > Device Info”.
Copy the contents of the information window (it may take a few moments for the information to appear), then open your web browser and paste the information into your reply.
Yes, I am running Ubuntu 12.04: Linux honolulu 3.13.0-44-generic #73~precise1-Ubuntu SMP Wed Dec 17 00:38:38 UTC 2014 i686 i686 i386 GNU/Linux
There are two sound cards: An internal one and a USB soundcard.

PS to my last reply:
The sound system is set to use the USB-card
CM106 Like Sound Device
Analog Surround 5.1 Output
You seem to have the built-in device listed in the Audio Device Info ( HDA Intel: ALC269VB Analog (hw:0,0) ).
Are you showing “Applications” in the “Recording” tab of pavucontrol?
Did you install pavucontrol recently? Sometimes you need to reinstall pavucontrol or pulse to make it behave, especially on old versions of Ubuntu.

Solution
Reinstalling pulseaudio and pavucontrol did not help.
However, when in pavucontrol → configuration I switch the internal sound card off, I can record from the usb-sondcard as intended.
However, Audio Device Info in Audacity → help still shows
Available recording sources:
0 - Headphone Mic:0
1 - Internal Mic:0
and the Audacity Recording Device pulldown shows only microphones. Is this an Audacity bug?
The version I use is Audacity 2.1.0-alpha-Jan 20 2015
Anyway, thanks for help!

I don’t understand why the recording devices are displayed like that in the Device Toolbar.
I also don’t understand why you have an alpha version of Audacity and not a release version.
What is the exact version of Audacity, where did it come from, and how did you install it?
The version is, as I said in my last post, Audacity 2.1.0-alpha-Jan 20 2015.
It was automatically installed by the Ubuntu Update manager. That happens quite offen, nearly daily.
I guess that you must have the “nightly PPA” in your sources list (Audacity Daily Build : “Audacity Team” team)
Alpha versions are not intended for production work. They are intended only for testing and development.
What I would suggest is that you completely uninstall Audacity using your package manager, then remove the PPA from your sources list. Reload the available packages, and reinstall Audacity. That should give you the official Ubuntu release version of Audacity.
Then go to “home//.audacity-data” (note that this is a hidden folder), and delete everything in that folder.
The restart your computer.
You now have a fresh installation of the official (supported) Ubuntu release version of Audacity.
Any difference in what appears in the device toolbar?
I’ve known it happen on older Ubuntu versions even if you merely enable additional sources in “Software and Updates”, without explicitly going to Audacity Daily Build : “Audacity Team” team and adding the Audacity PPA. When you then go to the “Ubuntu Software Centre” and search for Audacity, you get offered the alpha version to install and then you get offered the alpha update with each system software update.
The audio device list “could” be a bug with HEAD used in Ubuntu 12.04. The officially supported Audacity version for 12.04 is only Audacity 2.0.0, which is very old now.
When you said
The sound system is set to use the USB-card
where did you make that change?
Gale
I now removed audacity and audicity-data completely and asked the synaptic package manager to install audacity.
I get an alpha version again.

You should open Software and Updates (probably in Settings) and make sure you have removed any Audacity PPA’s that are listed on the “Other software” tab: fballem/Software 12.04 - Ubuntu Wiki.
If you are using Synaptic, mark Audacity for “complete removal” then “Apply”.
Then when you search for Audacity in Synaptic, look at “latest version”. It should say “2.0.0-1”. If you are still seeing 2.0.6-alpha, try Force Version: SynapticHowto - Community Help Wiki.
Or back up your data, remove Ubuntu 12.04 and install 14.04. Then when you go to Ubuntu Software Centre (or Synaptic, if you install it) and look for Audacity you should be offered 2.0.5 release.
