Enable some audio alarms to override low volume setting.

[GoogleCodeExporter]

Which board (stock / gruvin9x / sky9x / Taranis) are you using?

Taranis

What is your openTx FW version?
r2688

What is your openTx EEPROM version?
215

What steps will reproduce the problem?
1. Enable a low audio volume in general
2. critical alarms will also have low volume
3.

What is the expected output? What do you see instead?
It would be nice that critical alarms could override a low audio volume setting 
and have a loud volume in any situation.

Please provide any additional information below.

What I missed is the possibility to give some alarms the ability to override 
the volume settings and sound at full volume no matter what.

I assigned the volume control to my left slider, and sometimes had very little 
volume in order to not annoy other pilots with my vario or altitude readings. 
As there was quite some cheering and laughter at times, I missed critical stuff 
like motor timer alarms or RSSI alarms. 

There should be options in the general settings of the radio to deactivate 
volume reduction on several alarms like TX/RX voltage, RSSI, Inactivity, and 
this option on every alarm or sound activated via custom functions.
This would be perfect.

Not really possible, as for example when using headphones alarms playing at 
full volume would destroy your ear...

Well, then what about an option for the max volume of critical alarms?

Each alarm can be either "regular" or "critical". Regular alarms have the 
volume that is just set at the moment, while critical alarms override that 
setting and always have the volume which is definded in the "critical alarm 
volume setting".

Ok, which are critical alarms ?
System alarms al all critical depending on circumstances...
Here is the list of system sounds:

transmitter battery low
inactivity alarm
throttle warning
switch warning
bad eeprom
Welcome to open tea ex!
A1,low
A1,critical
A2,low
A2,critical
RF signal, low
RF signal, critical
radio antenna defective
telemetry lost
telemetry recovered

Apart "welcome to opentx" I will say they are all critical.
So, which is the sense to assign different volume to some of them ?

I agree, everything the radio says I want to hear. If I don't want to, it means 
it's not needed but uselessly distracting and gets deactivated.

The system alarms are all important, correct. 

Vario sounds, readings of current, voltages, altitudes, timers, temperatures, 
flight modes, sounds issued to the position of specific switches, stuff like 
this which does not warn me about a critical condition, but informs me when I 
choose it, should have the option to be played at a lower volume.

When I activate these options once in a while at full volume in order to know 
tmy altitude eor battery voltage, it looks like I want to show off with my 
Taranis' abilities, so I generally have my volume low and barely audible to 
bystanders.

But this, as explained above, has the risk of missing critical alarms.

Right now, I can only choose between annoying the hell out of my fellow 
clubmates and be sure to be aware of critical alarms, or to be moderate with my 
noise, but miss alarms.
It would be nice not to be in this dilemma.
