Applet should not set volume on startup (1.50 KB, patch)
2010-02-02 15:21 UTC, Bastien Nocera 		committed Details | Review

Description Lennart Poettering 2010-01-14 01:21:48 UTC 
for some reason g-v-c-a seems to reset the volume (and clamp it to < 100%) when the default device changes. Seems to be some kind of feedback loop left over.

see http://www.pulseaudio.org/ticket/756#comment:4 for a way to reproduce this.

Also, as a side note g-v-c-a should show the same volume range that g-v-c shows, i.e. extended to 150%.

Applet should not set volume on startup

When the applet sets its initial value, if the value is different
from the default, we'd set the scale value. Which would then
feed back into the value-changed for the scale, and sometimes
clip the value.

We shouldn't touch the sound on startup, when setting the
scale's initial value.
Comment 2 Bastien Nocera 2010-02-02 15:22:29 UTC 
Having the status icon use a wider scale would mean UI problems. Best
investigated as a separate issue.
