Another addition, I don't know if the original hiss bug is related to the one w've been discussing in recent comments but:
While the hiss thing and sound being disabled issue was fixed, there a remaining symptom or call it regression: If you're using 12.04, you might notice that when you login the sound is at very low volume even thought the volume bar is at a high position. To reproduce the issue: - Logout - Login back - Open TOTEM - open a video or audio file --> Do you hear any sound? Yes, but very low. Workaround it: - Type: Function key + Mute key - Type Function key + Volume UP / Volume Down. --> Recovred? Yes, the volume is back to its correct value. I must point to the fact that this applies to a laptop. I don't know the bug is reproduceable in desktop machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/897427 Title: [Advent 4211, Realtek ALC1200, Green Headphone Out, Rear] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/897427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
