Hello,
I am facing the following problem:
I carried out the following commands.
However, the result is no sound.
========
$ cat sounds/alsa/Front_Center.wav >/dev/dsp
========
I do not understand a reason to become this result.
The following is the contents of /proc/asound.
Thanks for any help.
$ for i in `find /proc/asound/ -type f`
> do
> echo === $i ==
> cat $i
> echo
> echo
> echo
> done
