Title:
No sound capturing possible - only noise - no hardware issue
Status in “pulseaudio” package in Ubuntu:
Confirmed
Bug description:
Since my update to KDE 4.10.0 (Kubuntu 12.04 backports) sound
recording is not possible anymore.
All I hear is hard noise, no matter what microphone I use (analog,
usb, …). I recorded my screen so you can see what's happening:
http://youtu.be/4YM3oDcl7K4
I record sound using Audacity, so you can see the noise. Then I use
KMix and the Audiosettings software to change several configuration
settings.
I booted Kubuntu 12.04.1 from CD-ROM (installation disk) to check if
it is a hardware issue, however recording works fine using the live
system.
Please let me know if I can provide more helpful information.
