so to be clear, you're saying that instead of lowering the volume it just mutes it?

I've seen this. Also, the locked stereo sliders have a tendency to come unlocked, without touching the unlock widget. Also possibly related: SELinux reports: The /usr/libexec/mixer_applet2 application attempted to change the access protection of memory (e,g., allocated using malloc). This is a potential security problem. Applications should not be doing this. avc: denied { execmem } for comm=mixer_applet2 egid=500 euid=500 exe=/usr/libexec/mixer_applet2 exit=-1063571456 fsgid=500 fsuid=500 gid=500 items=0 pid=23413 scontext=system_u:system_r:unconfined_t:s0 sgid=500 subj=system_u:system_r:unconfined_t:s0 suid=500 tclass=process tcontext=system_u:system_r:unconfined_t:s0 tty=(none) uid=500 Oh, and BTW, sound is broken for some applications on my system at the moment. See: #281711
I'm seeing this too. For me, it's not just using the mouse wheel on the mixer applet. I've got a Dell Multimedia USB keyboard with a round knob thing for volume control and spinning it too fast causes the same problems. (Kudos for getting this working in the first place though!) It seems to be a timing issue. If I scroll the mouse wheel slowly or the knob slowly, things work better, but perfectly. Too fast and weird things occur. I've seen the volume go up instead of down, mute, locked left right levels become unlocked, etc. It's really nonsensical. I opened the full mixer to observe what happens to it while I scoll the mouse and the master levels jump around randomly.
I should add that I'm on x86_64, with a SB Live CT4780 sound card. Up to date f8t2 plus todays updates.
Bastien, is this the thing you fixed already?
Yep, that's a dupe. *** This bug has been marked as a duplicate of 295311 ***
