I am also having this exact same issue on a Thinkpad R61 with the following hardware:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) Codec: Conexant CX20549 (Venice) It's as if the sound device is switching off when not in use and then switch back on when its needed. IMO this feature (if it is a feature) should be disabled and the audio device should remain active all the time. -- PulseAudio channeling motherboard signal transmissions, popping audio, lagging audio https://bugs.launchpad.net/bugs/449723 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
