Public bug reported: Binary package hint: linux-image
Kernel 2.6.32 no longer gives the correct volume range information about these speakers. It works fine in karmic. This is really an upstream bug report, I have filed it here: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4803 With kernel 2.6.31 and libasound 1.0.20 I got perfect volume ranges for my Logitech Z-10 USB Speakers, -41,00 dB to 1,24 dB feels just about right. When I upgraded to 2.6.32-rc6 I didn't get any range information at all until I upgraded to libasound 1.0.21. Now I'm getting completely bogus volume range information, 0 dB to 3 dB ProblemType: Bug AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
