I think you may be correct about it being an ALSA Driver bug. The information from http://pulseaudio.org/wiki/PulseAudioStoleMyVolumes gives more detail on the situation,
in summary: "PulseAudio depends on the correctness of the dB information the ALSA drivers export .... If you are experiencing distortions/clipping even though the inner volumes are set to 0dB, then this means that the dB information your ALSA driver exports is simply incorrect. In this case please file a bug against your audio driver and ask them to correct (i.e. shift up) the volume scale of that volume control." Go ahead and read that article, and see what you think. Assuming it is an alsa-driver i believe the proper command for debug info is "apport-collect -p alsa-base" in a terminal. -- master ALSA volume slider does not affect actual volume https://bugs.launchpad.net/bugs/514158 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
