            Bug ID: 366032
           Summary: plasma-pa should allow to select the sink for volume
                    control
           Product: plasma-pa
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
          Assignee: now...@gmail.com
          Reporter: niels_...@salscheider-online.de
                CC: plasma-b...@kde.org

Currently, plasma-pa just sets the volume of the default sink when the volume
keys on the keyboard are pressed. This is not necessarily what the user wants
if he has a bit more complex setup.
It would therefore be good if the sink for the volume control could be
configured in plasma-pa's KCM.

For example, I have this in my default.pa:

load-module module-remap-sink sink_name=headphones channels=2
master_channel_map=front-left,front-right channel_map=front-left,front-right
remix=0 sink_properties=device.description=Headphones
load-module module-virtual-surround-sink sink_name=vsurround master=headphones
hrir=/home/olesalscheider/.ir.wav
sink_properties=device.description=VirtualSurround
set-default-sink vsurround

This splits two channels of the sound card and creates a "headphone" sink from
them. The other channels could for example be connected to a surround sound
system but I do not use them currently.
Then it creates another sink (vsurround) with the "headphone" sink as master.
This sink computes virtual surround sound from its input signals and passes the
generated signal to the master.

I have set "vsurround" as my default sink because I want all new streams to go
there by default. But I have moved some manually to "headphones" where I do not
want the virtual surround effect (e. g. for music).
When I now press the volume keys I want them not to change the volume of the
"vsurround" sink but the volume of the master sink. Because otherwise the
volume of the streams that I moved to "headphones" is not changed.

Reproducible: Always
