Binary package hint: kmix
I'm filing this against kmix but it may actually be amarok that is the problem I'm not sure how to diagnose further. While working today with amarok running in the system tray I accidentally hit Win+M instead of CTRL+M. I've since discovered that this is a global shortcut for 'Mute Sound' The result was that amarok is muted and I am unable to unmute it. Sound is fine in realplayer and kaffeine which makes me suspect it may be amarok that is at fault. If I try to play an mp3 then amarok appears to be playing since the progress meter moves through the track and the animated bar at the bottom of the amarok window is responding but I can't here anything.
I've checked kmix and alsamixer and both display Master and PCM as unmuted. The hotkeys to set volume or mute sound on my laptop are still working and kmix is responding to those but still no sound comes out. I'm pretty baffled by this. I think it is related to bug #69352 which describes similar symptoms and is linked to an upstream kde bug here http://bugs.kde.org/show_bug.cgi?id=136378. I have tried the work arounds posted in the kde bug tracker but none of those made any difference for me. I've also looked into kmixrc and kmixctrlrc which I will attach in case it helps. The contents of both files look reasonably sane to me but I'm no expert in this area. I've also tried completely reinstalling amarok and kmix including manually removing kmixrc and kmixctrlrc to see if that would rewrite some sensible values. The attached files are from following this reinstall.

My laptop is Lenovo 3000 N100. I am running a fully up to date install of Kubuntu Feisty as of 10/04/2007. I am at a complete loss how to rectify this, any insights would be appreciated. If you need me to try anything or attach any other files or outputs just ask. I saw another kmix bug that asked for the output of amixer so I'll give that as well in case it's any use.
Assigning this to amarok since every other sound related app I've tested appears to be fine. I guess this means it probably needs to be passed upstream but I don't know how to do that within launchpad. It seems as if Amarok is just ignoring kmix but that's a complete guess. This bug is in need of some triage but I've pretty well exhausted my knowledge. If someone can tell me what needs doing I'll happily do it.
