New trigger showing group and index of sound currently playing. Expansion of possibilities for working with sound

Is your feature request related to a problem? Please describe.

My character have several playsnd controllers, that playing voice in one state. If one contoller activated, then the second should not activate. On current moment I solve the problem using a variable:

[State 1300, Playsnd 1]
type = playsnd
trigger1 =  var(1)!=1300
trigger1 = <desired condition>
trigger1 = var(1):=1300
value = 540,random%4
channel = 0

[State 1300, Playsnd 2]
type = playsnd
trigger1 =  var(1)!=1300
trigger1 = <desired condition>
trigger1 = var(1):=1300
value = 340,random%4
channel = 0

When the value of a variable (var(1)) does not match the state number, the variable is reset. In principle, this method works perfectly. But a special trigger would be more convenient for this. Something like:

Issoundplaying(340,1)

Where 340 is group number of the sound. 1 is the index of playing sound. Trigger Issoundplaying(340,-1) will return 1 if sound with any index from group 340 is playing.

And just ideas on what triggers can be added for working with sound:

• Trigger showing which audio channel is active (sound is playing) and which is not
• Trigger showing what sound is playing on what channel
• Trigger showing the number of ticks remaining to play the current sound (something like animtime, just for sounds)

Also, on current moment playsnd controller may have only 2 priorities: low or no priority. I suggest introducing a new parameter for playsnd. Something like sndpriority. Similiar to sprpriority, only for sounds. Sound with higher priority can interrupt sound with lower priority. And can't be interrupted by sound with lower priority.

How about the ability to add an echo parameter to any sound, not only KO sound?
