[Solved] Sound advise

[AndyGable]

Uhmmm... some time ago, stevedee proposed using the "Screen" Class of "gb.ncurses" Component.
Try:

Public Sub Main()

  Screen.Beep()

End

I have tried your recommendation but I kept getting a error

ERROR: #63: '&1.&2' is incorrectly overridden in class '&3'|Screen|Height|Screen

If I remove the gb.ncurses the application runs with no issues.

You have to use "gb.ncurses" with a command line interface project (no graphics Components):

Public Sub Main()

[AndyGable]

No I was using it with a GUI qt5

[vuott]

...and by using a command line interface project (with gb.ncurses obviously) ?
Does it work ?

Try:
play -V3 -n synth 0.1 sine 880 vol 0.4

vol 5 means 5 times the normal volume which clips to a DC voltage.

I tried this one and I got the following show up in the console of the Gambas enveroment.

play WARN alsa: can't encode 0-bit Unknown or not applicable
play:      SoX v14.4.2
play INFO nulfile: sample rate not specified; using 48000

play INFO sox: effects chain: vol          48000Hz  1 channels
play INFO sox: effects chain: output       48000Hz  1 channels

and no sound

OK, That's almost exactly what I get, with the beep very audible. The only difference is
Output File : 'default' (pulseaudio)
Do you have pulseaudio installed. (I have no idea why it should be needed, btw)
tb

OOPS! I also get this at the end:
In:0.00% 00:00:00.17 [00:00:00.00] Out:4.80k [ -====|====- ] Clip:0
Done.

BTW, A4 is one of the most annoying sounds in the universe.
Try C3 523.25Hz

How about installing beep?

sudo apt install beep


beep

[AndyGable]

How about installing beep?

sudo apt install beep


beep

Yea I did that and and it worked but it was the quietest beep ever lol

I need to work out how to beep the Dynakey built in speaker and not the one on the motherboard now I can make the beep sound.

Dim SpeakerData As String = Null
SpeakerData = "speaker-test -t sine -f 1000 -l 1 & sleep .2 && kill -9 $!"
Shell SpeakerData 

There is no need for = Null, you could have just followed the equal sign with "speaker - test -t.....". Better still: -

Shell "speaker-test -t sine -f 1000 -l 1 & sleep .2 && kill -9 $!"

Which works for me
************************************

shell "play -n synth 0.1 sine 880 vol 5"

You are correct, it doesn't work, and I have no idea why.

The problem with the above is the systems I am using do not have any sound cards on them they only have the PC speaker.

Did you miss my post? It requires stdout or the play command does not exit so use "&" or "For Output" when using gambas Shell process then it can continue

Shell "play -n synth 0.1 sine 880 &"

or

Shell "play -n synth 0.1 sine 880" For Output

They both work fine here

Shell "play -n synth 0.1 sine 880 2>/dev/null &"

if you want to divert the text output (stderr) to null

Sorry Bruce I did miss your post

and it works perfectly

NOW If I am reading this information right
Speaker

The 5953 includes a built‐in speaker. By default, it sounds key clicks, but it can
be programmed to sound tones under control of the application program.

The speaker is tied to the speaker control of the host terminal so that whenever the
terminal speaker sounds, so does the 5953 speaker


I should not have to worry about the DynaKey Speaker it should work with the current Shell "play -n synth 0.1 sine 880" For Output. I will have to test this in the morning when I am near my NCR machine again and I will let you all know.

this is the NCR Dynakey Manual (https://manualzz.com/doc/55220224/ncr-r ... manual#p15)
