Volume level is not remembered for role+output pairs

[Marcus Tomlinson]

According to https://wiki.ubuntu.com/Sound: "the volume for media played through headphones, the volume for media played through speakers, and the volume for a ringtone played through speakers, should be three independent volume levels"

This is not currently true. For example,
- if I set the volume for the headphones,
- unplug the headphones,
- set a new volume for speakers (e.g. max volume),
- then plug the headphones back in,
- the volume doesn't switch back to my previously set headphones level (e.g. my ears are blasted at max volume).

I just wanted to add another bug but this one is pretty close to what I wanted to report. As You see in the attached photo on Android we are able to change three volume sliders.
Two days ago before falling asleep i listened to uRadio app: VERY quietly. Suddenly I realized that the radio volume is the very same volume thats is gonna try to wake me up a few hours later which can be a mission impossible.
Same stuff about incoming call volume and alarm clock: If we make the ringing tone silent to be able to sleep, so thats nobody wakes us, the volume of the alarm clock is silent too :-(

I've noticed recently that "Ringtone" and "Message received" sounds are too silent, so it's easy to miss incoming call or SMS, event if sound indicator shows 100% volume!

After some troubleshooting I discovered that "Ringtone" (and "Message received") has same sound level as when playing with Music app! So, I launched some music track (without headphones), increased volume to 100% (through sound indicator), because it was around 40%, and now "Ringtone" and "Message received" sounds are clear and loud as I would expect.

So, even sound indicator shows 100%, "Ringtone", "Message received", and "Music" app volumes are sort of different kind.

It's kinda unsure what does that volume indicator.. indicates. Sound that I hear during the phone call?

@GTriderXC, Vincas: this is really strange becuase:
AFAIK:
- message received sounds should use alert role
- Music/YouTube/... apps should use multimedia role
- during calls the phone should use phone role
- alarms should use alarm role
- feedbacksound role is used when there are no sounds playing (always muted)
indicator-sound always shows current active role volume (each role has a volume). So if indicator-sound showed 100% volume maybe another role was playing in background (with 100% volume), when no apps are running it defaults to alert volume. When an alert sound is played a current playing multimedia volume sound is decreased (pulseaudio ducking module) and restored after the alert sound has finished playing.
Could you please open another issue if indicator-sound is not working as I described for you? Maybe a reboot will help if a process like media-hub crashed.
Using ' pactl list sink-inputs ' command you can see current active role (media.role) and associated Volume value (ignore feedbacksound)
