Dear Ptitjoz,

Just do a search of the forum. Peter and I have posted mp3, soundfont, DSP, wav and other players, all using different methods to produce sounds. Rather recently I posted soundfont and bleep programs.

With kind regards,

PS. I found some links and attached a few sources:

Hello

On my ASUS T101HA laptop where I installed Lubuntu 18.04, I do not think the beep command works on this laptop
echo -ne '\ 007' does not work
however, I can listen to mp3

when I try to compile bleep I have this return

Compiler error:

In file included from bleep.bac.c:2:0:
bleep.bac.h:7:0: warning: "O_RDONLY" redefined
#define O_RDONLY (0)

In file included from /usr/include/x86_64-linux-gnu/bits/fcntl.h:61:0,

#define O_RDONLY 00

Dear Joz,

You might have to install osspd or an oss or alsa compatibility package to get the /dev/dsp device. Then beep should work, too.

You could install:

sudo apt-get install osspd-alsa and the compatibility bit.

I also found a note in one of my own progs:

For sound, you might need to load the OSS
' compatibility module first  so the program can find
' the /dev/dsp device file:
' install oss-compat (sudo apt-get install oss-compat) and then
' type sudo modprobe snd-pcm-oss in a terminal

With kind regards,

PS. I found a wave player I wrote in March: bwplay.
