    Recording from ''Internal Audio Analog Stereo' (Pulse+Alsa)

    [Ubuntu 10.10]

    Hello,

    I am experiencing troubles recording from Internal Audio Analog Stereo in pavucontrol. There is microphone 1 (external) and microphone 2 (built-in notebook internal). I am certain I have chosen the correct input port in pavucontrol, have chosen the correct input device under Recording for the application I am using, and unmuted the microphone. AI can record from both "Monitor of Internal Audio Analog Stereo" and "Monitor of RV710/730 Digital Stereo (HDMI)". It works with both Skype and Audacity. Audio playback works perfectly fine as well. Unmuting the microphone under playback with alsamixer, what the microphone records gets outputted to the speakers, so I can confirm the microphone itself works.

    "arecord -D hw:0,2 -r 48000 -c 2 -f S16_LE" reports:
    arecord: pcm_read:1692: read error: Input/output error
    Recording from the mic with audacity does not work as well.

    Recording from Internal Audio Analog Stereo did work previously, then stopped working. I think my problem may be related to misconfiguration (perhaps having both pulse+alsa, I do not know much about this), or wrong access permission (my user am added to the pulse-access group, however). Being able to select output for every application with pavucontrol is very convenient, so I would like not to uninstall pulse.

    Output of various commands:
    aplay -l

    Re: Recording from ''Internal Audio Analog Stereo' (Pulse+Alsa)

    Did you ever figure this out? I am trying to use sound recorder to record from the stream. First I start VLC and start Sound recorder. I open pavucontrol and start VLC. I see VLC show up in the Volume manager but the sound level isn't working, but I try anyway. I set the sound recorder to record and in the recording tab select sound recorder to record from Monitor of internal audio analog stereo. But Sound recorder doesn't record anything.
