  • Beep on WIndows 11

    From Rob Cliffe@21:1/5 to All on Sat Nov 11 22:49:51 2023
     Apologies if this is not a Python question.
    I  recently moved from a WIndows 10 laptop to a Windows 11 one.
    Although there is nothing wrong with the sound on the new machine (I can
    listen to podcasts and watch videos), I find that outputting "\a" to the console (aka stdout) no longer beeps (or makes any sound).  This is true whether I print "\a" from a python program, or "type <a-file-containing-a-bell-character>".
    I have found via Google workarounds such as
        os.system("rundll32 user32.dll,MessageBeep")
    but it is a trifle annoying to have to modify all of my programs that beep.
    Can anyone shed light on this, and perhaps give a simpler fix?
    Best wishes

    HI,
    I would first check the properties of the terminal, then the system configuration relating to the system beep. It can be disabled.
    You can find some tips here: <https://superuser.com/questions/10575/turning-off-the-cmd-window-beep-sound>

    There are several purposes. I can't say which of these are relevant to
    the OP, but some or all of them could easily be.

    * A very very simple notification that can be triggered by any program
    * An audio cue that is not routed to your regular audio system (good
    if you use headphones but are AFK)
    * An extremely low level signal that requires little-to-no processing power
    * An emergency signal that does not even require a CPU (probably not
    in this instance though!)
    * Imitating a pre-existing audio signal that works by beeping

    Depending on what's needed, a more complex system might suffice (for
    example, I cover the first two points by having an entire separate
    audio subsystem with its own dedicated speakers, which I can invoke
    using VLC in a specific configuration); but a basic beep is definitely
    of value. I suspect in this situation that the first point is
    important here, but it's up to the OP to elaborate.

    (Note that the "no CPU emergency sound" option usually requires a motherboard-mounted speaker or speaker header, which not all have
    these days. Sad.)

    It's a simple way for a terminal-based program to alert (hence '\a') a
    user or an operator that their attention is requested or required.

    Recently, I wanted a program to beep.

    In the old days, with a BBC micro, that was simple. It had 3 tone
    channels and 1 white noise channel, with control over frequency,
    duration and volume, beeps on different channels could be synchronised
    to start at the same time, there was a sound queue so that the SOUND
    command returned immediately, and there was an ENVELOPE command for
    controlling the attack, decay, sustain and release. All this on an 8-bit machine!

    My current PC is way more powerful. 64-bit processor, GBs of RAM, etc.
    Python offers winsound.Beep. 1 tone, no volume control, and it blocks
    while beeping.

    I learned to make a computer beep using the programmable timer chip
    (8254?). Send it signals on the I/O port saying "timer chip, speaker
    signal, counter = N" (where N is the fundamental clock divided by the
    frequency I wanted), and then "speaker, respond to timer chip". Then
    you wait the right length of time, then send "speaker, stop responding
    to timer chip".

    Of course, I had a bug in the "wait the right length of time" part,
    and my program stopped running.

    My family was not amused.
