Dear Maintainer,
I recently upgraded from Debian 11 (Bullseye) to Debian 12 (Bookworm) and
experienced a regression with PulseAudio. After the upgrade Amarok (as
distributed with TDE, not KDE) plays at a significantly lower volume level than
before the update, to a point where it is barely usable. I experimented with
several other applications - VLC, Firefox, mplayer, xine - and for all of them
volume levels behave as expected and are sufficiently loud. With Amarok it seems
that the volume is no longer linear. In the lower range of the scale differences
between volume levels are negligible. For example, percieved difference between
changing Amarok volume from 28% to 48% is smaller than when changing if from 64%
to 68%. (Note that changing Amarok's internal volume does not change its
corresponding PA volume slider in pavucontrol.) This problem is present both
when using Amarok's xine backend and its alsa backend, which might suggest that
this is a problem in Amarok. However, since the problem did not occur under
Debian 11 and Amarok and all of TDE is built from the same sources under Debian
11 and Debian 12, I believe this bug was introduced by a change outside of
Amarok. I also tested this under a new user account with fresh configuration to
ensure this is not caused by a stale user configuration from before the upgrade.
