Windows 10: How do you set multimedia keys to affect another audio source or music player's volume?

How do you set multimedia keys to affect the volume of another audio source or music player's volume?

Volume Question for Music Players

Have you tried messing with these settings?

 

N95 Volume Key, Music Multimedia Key & Battery Drain

My volume keys (camera zoom keys) on the side of the phone work intermittently. They don't work for a day or so then fine for a few days and so on.

When the volume keys dont work I also notice the following:

- "Press Unlock to activate keypad" keeps appearing when the keypad is locked without me touching the phone

- cant adjust volume in calls (except using the centre navi key)

- cant zoom in/out in camera

- music multimedia buttons dont (play, pause, fwd, rwd, stop)

- music multimedia button does not launch music player

- battery runs out very quickly; energy profiler shows phone uses over 1w instead of 0.2w it normally runs at.

I have the latest V21 firmware installed.

Any ideas?

 

Audio sources default / startup volume

The audio is integrated on my Asus M5A99FX Pro R2.0 motherboard and is listed as Realtek ALC 892 8-channel high definition audio CODEC. The problem occurs randomly, but I think I sometimes see a correlation with opening a new browser tab. I run both Firefox and Chrome concurrently, and both are up-to-date. The last time it seemed to have occurred with opening a new tab in Firefox, but as I said, it often happens randomly. Event viewer is not logging any Firefox or Chrome errors.

From the crash information I posted above, it appears that it is a Windows fault rather than an application as suggested by the error fault information, which is why I'm looking for a possible work around. Event viewer show the earliest error occurred on 4/14/2017 and was uploaded via error reporting to Microsoft. I was hoping to find a way to keep the affected input channels from coming back on to the (loud!) speaker level I use for other other audio input sources. The volume mixer's channels come back on to the speaker level setting, not to the top end of the channel's volume slider. Not all slider volumes are affected when this happens. The line in channel always does it, but system sounds and email (Thunderbird) channels are usually not affected.
