The cat <file> >/dev/audio command plays *.au sound files I believe, but that type of sound file probably isn't even on your system. Actually, AFAIK, cat <file> > /dev/audio (or /dev/dsp, if applicable) will play any uncompressed PCM audio file (*.au, *.wav) at 8000 Hz. I'm not sure if it has to be signed or unsigned, though.

Re asofel and otaconx: Any block of text interpreted by /dev/audio tends to have a rather uniform sound, kind of a feathery leaves rustling in the wind noise. This is because ASCII text is actually printing out a rather limited range of values; after all, a character value lives in the range 0-255, but only 96 of these are on a QWERTY keyboard.

This will map the /dev/audio or /dev/dsp file to the new Audio Server system. Fire up the terminal and get into root mode with sudo su. Then, I'm going to cat /dev/urandom and pipe the output into padsp and use the tee command to send the data to /dev/audio. You'll get a ton of garbage in your terminal, so you may want to redirect to /dev/null.

I love 'cat /dev/random > /dev/null', it's the best way to waste energy and generate heat. It's basically screaming to the void. cat /dev/zero > /dev/null discards data with higher throughput since /dev/zero is a lot faster than (u)random (but the data is boring). I don't know what is the definition of boring in your dictionary, but I'm just ...

https://en.wikipedia.org/wiki/Open_Sound_System
The Open Sound System (OSS) is an interface for making and capturing sound in Unix and Unix-like operating systems. It is based on standard Unix devices system calls (i.e. POSIX read, write, ioctl, etc.).The term also sometimes refers to the software in a Unix kernel that provides the OSS interface; it can be thought of as a device driver (or a collection of device drivers) for sound ...
