Package: pavucontrol Version: 2.0-3 Severity: normal Dear Maintainer,
in pavucontrol, the volume sliders show two values, percantages and dB values. These values however, do not match. 50 % volume should be about −6.02 dB, but pavucontrol shows −18.09 dB. 25 % volume should be about −12.04 dB, but pavucontrol shows −35.81 dB. 10 % volume should be exactly −20 dB, but pavucontrol shows −59.68 dB. My ear tells me that the resulting volume corresponds to the dB values, not the percentages, so when I set the slider to 50 %, I actually get 12.5 %. So I guess, this is what happens: pavucontrol uses a linear slider, then converts the values to dB using an incorrect formula, and then uses the wrong dB values to set the volume. -- System Information: Debian Release: 8.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/2 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages pavucontrol depends on: ii libatk1.0-0 2.14.0-1 ii libatkmm-1.6-1 2.22.7-2.1 ii libc6 2.19-18+deb8u3 ii libcairo-gobject2 1.14.0-2.1 ii libcairo2 1.14.0-2.1 ii libcairomm-1.0-1 1.10.0-1.1 ii libcanberra-gtk3-0 0.30-2.1 ii libcanberra0 0.30-2.1 ii libgcc1 1:4.9.2-10 ii libgdk-pixbuf2.0-0 2.31.1-2+deb8u4 ii libglib2.0-0 2.42.1-1 ii libglibmm-2.4-1c2a 2.42.0-1 ii libgtk-3-0 3.14.5-1+deb8u1 ii libgtkmm-3.0-1 3.14.0-1 ii libpango-1.0-0 1.36.8-3 ii libpangocairo-1.0-0 1.36.8-3 ii libpangomm-1.4-1 2.34.0-1.1 ii libpulse-mainloop-glib0 5.0-13 ii libpulse0 5.0-13 ii libsigc++-2.0-0c2a 2.4.0-1 ii libstdc++6 4.9.2-10 ii libx11-6 2:1.6.2-3 Versions of packages pavucontrol recommends: ii pulseaudio 5.0-13 pavucontrol suggests no packages. -- no debconf information
