OK, thanks — can anybody else confirm if PA is indeed Debian's native
sound system?

Because if this is not the case, using ALSA output plugin can yield
better results.

I am using Ubuntu, and I can not reproduce this behaviour: cmus does

Volume (cmus application one) is not saved, however, and cmus does
start with 100% every time. I will try to address this.
