Well, I really appreciate the workaround proposed by Igor, great job, many
thanks! At least it has made sound to work more predictable.
However, I believe the issue is broader than just playing with the audio
group. Since it affects not 100% of users and some of them are used to hear
sound
I must admit I've spent huge amount of time figuring out what had caused my
Ctrl key to behave in such inconvenient way as described here :)
And eventually I see many people in Gnome bugzilla claiming it may be useful to
keep it as is. It definitely have to be fixed and work as user expects it
