How to change the volume of the amixer With a virtual dimmer

I have domoticz v 2020.2 beta current RPI, dzVents Version: 3.0.8
I use a USB audio card where I do volume control using the selector and sh scripts
#!/bin/bash
amixer sset 'Speaker' 2dB+
#!/bin/bash
amixer sset 'Speaker' 2dB-
or
amixer sset 'Speaker' 0% - selector - level 1
amixer sset 'Speaker' 100% - selector - level 10
How to change the volume of the amixer With a virtual dimmer.
What is the best way to do this ; amixer sset Speaker value to virtual dimmer%
Of course, it's best at dzVents
thank you for your help

How to change the volume of the amixer With a virtual dimmer.
Can you check if the dzVents command os.execute("amixer sset 'Speaker' 2dB+") does work ?

That's how it works
Code: Select all
return {
on = {
devices = {'Button'}
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'Volume up button ',
},
execute = function(dz, device)
if (device.state == 'On' ) then
os.execute("amixer sset 'Speaker' 2dB+")
dz.log ('volume up +2dB')
end
end
}

And what is the range of the dB+ and dB- ?
In other words if the slider of the dimmer goes from 0 to 100 how much should the dB do ?

Speaker [dB gain: -45,00, -45,00] - mute 0%
Speaker [dB gain: 0,00, 0,00] - full 100%
if gain = -45 and amixer sset 'Speaker' 2dB+
set gain = -43
I hope it's readable

So 100 = 0 and -45 = 0 ?
Is my conclusion that every 100/45 point of the dimmer is 1 dB correct ?

Yes, this is it

I changed sh scripts to one dzVents script and it works
Code: Select all
return {
on = {
devices = {'Volume'} -- Name of the dummy Domoticz selector
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'Volume control ',
},
execute = function(dz, device)
local vol = dz.devices('Volume')
if vol.state == 'Off' then
os.execute('mpc pause')
dz.log ('volume mute')
elseif vol.state ~= 'Off' then
os.execute('mpc play')
dz.log ('Set volume to selector level')
end
if vol.state == '25%' then
os.execute("amixer sset 'Speaker' 25%")
elseif vol.state == '27%' then
os.execute("amixer sset 'Speaker' 27%")
elseif vol.state == '30%' then
os.execute("amixer sset 'Speaker' 30%")
elseif vol.state == '35%' then
os.execute("amixer sset 'Speaker' 35%")
elseif vol.state == '40%' then
os.execute("amixer sset 'Speaker' 40%")
elseif vol.state == '45%' then
os.execute("amixer sset 'Speaker' 45%")
elseif vol.state == '60%' then
os.execute("amixer sset 'Speaker' 61%")
elseif vol.state == '70%' then
os.execute("amixer sset 'Speaker' 70%")
elseif vol.state == '80%' then
os.execute("amixer sset 'Speaker' 80%")
elseif vol.state == '95%' then
os.execute("amixer sset 'Speaker' 95%")
end
end
}
However, this does not give as much opportunity as a dimmer

can you try this after setting up a virtual dimmer in domoticz
Code: Select all
return
{
on =
{
devices =
{
'Dimmer', -- Name of the virtual dimmer
},
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'Volume control ',
},
execute = function(dz, item)
local percentage = 0
if item.state == 'Off' then
os.execute('mpc pause')
dz.log ('volume mute')
return
elseif item.state == 'On' then
percentage = 95
else
percentage = item.level
end
dz.log ('volume to ' .. percentage .. '%',dz.LOG_DEBUG)
os.execute("amixer sset 'Speaker' " .. tostring(percentage) .. "%")
end
}

Thank you for your help, but it doesn't work ok.
I added the mpc play command because dimmer did not start playback.
The script works so that it always sets the value of percentage max
no matter where the slider is
Code: Select all
if item.state == 'Off' then
os.execute('mpc pause')
dz.log ('volume mute')
return
elseif item.state == 'On' then
os.execute('mpc play')
percentage = 40
else
percentage = item.level
end
dz.log ('volume to ' .. percentage .. '%',dz.LOG_DEBUG)
os.execute("amixer sset 'Speaker' " .. tostring(percentage) .. "%")
end
}
Record in Log

item.dimTo(0).silent().afterSec(1)
else
local percentage = item.level
dz.log ('volume to ' .. percentage .. '%',dz.LOG_DEBUG)
os.execute("mpc play; sleep 1; amixer sset 'Speaker' " .. tostring(percentage) .. "%")
end
end
}

Now works in the slider range.
The level change works with a second delay but it is probably by sleep 1? I have a question
Why when the dimmer is OFF need to set the dimmer to 1 and per second to 0
Second question After setting the dimmer to OFF and then He is always 1% level Does it have to be this way?
Third question. If you delete the mpc play and pausa commands, you can eliminate delays?
Many thanks for your time and help

Answer 1+2: If you don't do this the slider will stay on the last level ==>> visual confusing

Yes, the sleep is only to ensure that the volume command does not interfere with the play.
Just experiment without it and you will see if it keeps working. I cannot test because I don't own the hardware.

Without mpc play support, pause Works as I wanted
