Please, attach output from 'arecord -vvvv /dev/null' and also from 'arecord -vvvv -D plughw:0 /dev/null'.

I don't get the cursor back after that. I did Cntrl-C to get the command line.

Thanks for all your help!

Comment 3 Bug Zapper 2008-11-26 05:42:37 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

Comment 4 Pedro Matiello 2008-11-30 17:48:04 UTC 
I have the same issue. Also, recording from gnome-sound-recorder is full of crack-like noises if something has been played in rhythmbox earlier (but if I mute the rhythmbox source in Pulseaudio volume control, it goes fine).

(I have changed the audio input source from Alsa to Pulseaudio in Gnome Sound Preferences. Before that, Sound Recorder locked on recording.)

I believe there's something going wrong between Pulseaudio and Alsa.

Comment 5 Pedro Matiello 2008-11-30 18:57:36 UTC 
Workaround: removing alsa-plugins-pulseaudio seems to have fixed the issues.

I'll keep watching this issue and test any relevant updates.
Comment 6 Lennart Poettering 2009-05-06 18:15:01 UTC 
Please provide the output of "pulseaudio -vvvvv" run in a terminal when this happens. (you might need to run pulseaudio -k first)
Comment 7 Lennart Poettering 2009-07-31 14:16:29 UTC 
Closing due to lack of response.
