The Headphone element is not the only element that affects headphone volume. If the Master element is at high level prior to plugging in headphones, and the to-be-restored volume for headphones is low, there will be a spike in the volume if the headphones are not muted, because the Master volume is initially too high. > > > Do pulseaudio store headphone volume and restore the user selected level > > > after restart/reboot > > > > Yes. > > Can the user dump database to verify pulseaudio had store the headphone and > speaker volume? > > eg. User want to set hp to 50% and speaker at 75% We don't have native tools for dumping the database contents. Pulseaudio supports three different database formats, the format is decided during building. The "tdb" and "gdbm" formats probably have some tools for examining the database contents. The "simple" format is homegrown, and doesn't have tools for dumping the database contents. The database is the file with "device-volumes" in its name under ~/.config/pulse, if you want to take a look. -- You are receiving this mail because: You are the QA Contact for the bug.
