I believe Daniel Chen set this to WontFix prematurely. This report isn't "wahh, I don't like how pulseaudio works." It's an actual bug.
When I set the volume with gnome's mixer applet or with pavucontrol, and pulseaudio's level reaches 15%, then Alsa's "Master" channel reaches zero. Therefore, at all levels below 15%, there is no sound at all. Alsa's PCM volume stays at 100% until pulse reaches 2% or so, and then PCM finally drops to 0%. Of course this has no effect, because Alsa's Master has been silenced the entire time. I'm guessing the intent is that Master should stay at a small, nonzero volume, until pulse is finally lowered to zero. This is happening on a Dell M6400 with Intel HDA: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) I've attached a screenshot of puvacontrol and alsamixer side-by-side at 15% volume. ** Attachment added: "Screenshot showing Alsamixer reaches 0% while pavucontrol is still at 15%" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/533921/+attachment/1762565/+files/volume_15pct.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/533921 Title: [lucid regression] HDA: pulseaudio volume control sets alsa master to 0 when still at 15% (incorrect db data?) -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
