--- Comment #22 from Vasco Almeida <vasquinhos13 at sapo.pt> ---
I can reproduce the issue Radics Péter is describing about Mono playbacks.
When speech-dispatch (Client #6 in pactl list clients) volume is not 100% or 0%
or less than 3% (~ -94dB), it sounds loud and distorted or rusty.


speech-dispatcher is a mono stream. I use flat-volumes = no.
Using Sabayon Linux media-sound/pulseaudio-5.0-r4.

About recording streams:
When I run 
env PULSE_PROP="filter.want=echo-cancel" mumble
if Mumble volume is no set to 100% or 0%, it picks lot of noise.
I dont have any issue change the volume when executing mumble (without
echo-cancel).
