Hello 龚韬, Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I noticed that you said "...and there is no longer any sound" after you said you muted. However, when you put electronic devices near your speakers, they made sounds. I'm curious as to what kind of sounds they made. Electronic devices, especially those with some sort of receiver (like cell phones, radios) make speakers give off sounds when in close proximity. So I fear this isn't a bug at all. Please describe the other devices you put near your speakers, and the kind of sound you heard.
The first link on google gave me this: http://www.mentalfloss.com/blogs/archives/10300 . Tell me if that's what you're experiencing, because that happens with all speakers. -- I can't mute fully. https://bugs.launchpad.net/bugs/194925 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
