Send signal to /dev/dsp

Hi!

I was wondering if I could produce a sound using console.

I was considering like a command:

echo "Some logical text here" > /dev/dsp

This would send that text to the soundcard output, right?

Well wrong. It doesn't work for two reasons.

Either the text does not tell the soundcard anything usable to do (or hearable) or it can't be written to soundcard output just that easily.

Thanks for any help on doing that!

Peace!

Type cat vmlinuz > /dev/dsp to hear the Voice of God.

*lol* -you did that? sorry it didn't do anything.
ok. BSF. does your sound work in X? if so you can play music at the console using for example "play". this program can play nearly everthing. first try "locate play" to see if its here. if you have a ogg/mp3-file somewhere around try "play music.ogg/mp3". wav should work too. i asume you have only one soundcard. else use the -d /dev/dsp1 switch.

My sound works. I can play all these files. I was just curious to see if I can send any signal to my soundcard and it would play it. Because that would be so cool. Also to my internal pc speaker if that was possible.

Any ideas on how and if thats possible?

I am not trying to get my soundcard fixed.... it works.....this is for educational and fun reasons only.

Thanks!

if you want to use the speaker there is a prog to do so. i dont know where- you have to search your distribution or the internet. maybe you'll need a kernel-module to be insmod'd to do so.
if want to get speech try software like recite (rather simple), festival or other.
