GUI Sounds - Offering sounds for specific actions

[questions2000]

NOTE
I decided to combine all of these into one post.
These probably should not be added unless the following suggestion made in this post is added to Rockbox.
https://forums.rockbox.org/index.php/topic,55331.0.html
The post in the link above is basically about offering the ability to be able to toggle specific sounds on/off.
The settings I will mention below would not be desired to be used by everyone so an on/off toggle would be needed if these were included.

Rockbox currently offers two action sounds when the setting "Headphone Keyclick" is activated.
The two sounds are CLICK & BEEP, which I find very useful.

OVERVIEW
This post is suggesting Action Sounds to be added to the following actions.
-Startup
-Shutdown
-Next/Previous (Forward/Back)
-Fast Forward / Rewind

I will make reply posts below for each of these items in list above, explaining a little more about them.

Thank You to anyone who reads any of this.

STARTUP / SHUTDOWN
Would make these two items separate sound settings, one for Startup and one for Shutdown, user may not want to hear/use both.
For these I would recommend using the startup and shutdown sounds from Windows XP.... just kidding
I would use the BEEP sound effect for both of these actions because it stands out more then the CLICK sound effect.
(BEEP = the same sound effect used to let user know they have reached the top or bottom of menu list)

STARTUP
This would obviously let user know that RB has been started / device has been turned "on".

SHUTDOWN
This one I think could be even more beneficial, to indicate that the device shutdown sequence has been activated.
This would be for if user has their screen backlight set to "Never" which means always "off" or is not looking at their screen.
If you hold down "Play" button to activate RB Shutdown, there really is no indicator to let user know that the device has actually been shutdown.
(If device has a hard drive, you can hear the drive spin down but not ideal and not present in SS drive based devices)
BEEP sound effect could give user an audible indication that Shutdown is being applied.


------------------------------------------------------------------------------------------------
NEXT/PREVIOUS (FORWARD/BACK)
I might not like this after/if this is added, but currently feels strange that there is no sound effect for these actions.
Would add CLICK sound effect for next / previous (forward / back) actions.


------------------------------------------------------------------------------------------------
FAST FORWARD / REWIND
(This one is probably too complex to add / also might be another one not desired once it is added, just an idea)
Currently with these actions there is the CLICK sound effect used for the button holds, which is probably all that is needed, but....
For example, if backlight is "off" or user is not looking at screen, was thinking maybe could be interesting to have a light repetitive click sound effect. 
Could also be nice if this light clicking sound effect gradually increases in speed/repetition along with the acceleration of the FF/RW increases.
Would give user an auditory indicator of the FF/RW action being performed along with the speed of the action.
Again, might be too complex to add.

STARTUP / SHUTDOWN

If voice prompts are enabled then you already get this.

Thank you
True, but if not using the voice prompts option, some kind of sound effect could be helpful to some users.
Again Startup may not be as important because device is "on" and any navigation right after will let user know the device is "on", Shutdown would mainly benefit from this, but again just mentioned Startup as well because they are kind of a pair.
