It _may_ be triggered by suspending/resuming, but definitely not in a systematic manner. I suspend and resume all the time and have only observed this issue in few occasions.

This is the second time i experience this. - I have external speakers connected to the hearphones plug of my laptop. Normally everything works fine. - All of a sudden, all sound seems to come only from the right channel, so I start checking my speakers and connections and everything's ok - Then I open Sound Settings; It shows the settings for "headphones". The "balance" setting is at center; yet if I go to "test sound" and I click the left "test" button i hear nothing (when I click the right test button I hear sound from the right). - I unplug the external speakers. Now the settings for "speakers" (meaning laptop's built-in speakers) show up. I do some tests and everything's fine - I plug the external speakers again. Now the settings for "headphones" show up again, and this time I can see that the balance is moved all the way to the right!!!!!! - I move it to the center and now everything works fine. So there are two bugs: 1. the setting for sound balance changes on its own initiative and moves itself all the way to the right without me having touched anything 2. in the sound settings window it doesn't show up correctly: it shows up as centered even if it is all the way to the right. Only after unplugging and replugging headphones it shows the actual value I know it sound CRAZY but it is exactly what happened. It's the second time, so it's definitely real.
