Public bug reported: Release: 9.10
After upgrade from kernel 2.6.31-16 to 2.6.31-17, my external microphone stopped recording, although it still works fine in 2.6.31-16. Playback of sound is no problem in all kernels. The problem also exists in kernel 2.6.31-19. I need to boot into kernel 2.6.31-16 in order to be able to record sound (i.e. Skype, Sound Recorder). You can find a description of the problem in my forum post here: http://ubuntuforums.org/showthread.php?p=8663649#post8663649 Please advise what technical data you need as I am not sure what exactly causes this problem. I only know it works in kernel 2.6.31-16, but not in the newer ones. Maybe his might be the cause of the problem? Right-click on the Sound Icon in the top right corner and check the following: In the hardware tab, it is set to analog stereo duplex, input is set to internal audio analog stereo (no other choice here) and the mic is NOT muted (playing with the volume doesn't help either) and output is set to internal audio analog stereo (again, no other choice) and connector is set to analog output (here I can switch to analog headphones or analog speaker, but makes no difference) I can choose between Microphone 1 and Microphone 2 in the input tab in kernel 2.6.31-16; this option is somehow gone in kernels 2.6.31-17 to 2.6.31-19 (i.e. only the option internal audio analog stereo is available) Thank you for your support!
