Package: aumix Version: 2.8-17 I find that many times I start aumix (in interactive mode) to adjust the volume slightly, and press a key (left/right) apparently before it's done initializing itself. As it's a small application, it doesn't take long to init, and I'm naturally not holding the key down it down for long time. This happens most often when the machine is loaded somewhat heavily, eg. after cycling through 10s of tabs in a bloated f!refox process. Actually, keypress during initialization doesn't seem to do it, just the keypress immediately after that. The volume immediately goes to 0.
I just reproduced this under strace -f.
Summary here with full gzip attached.
