Problem with /dev/dsp

[Aqlor]

Hey again guys,

I wanted to test some really interesting code I found online on http://www.arachnoid.com/signal_processing/fft.html

At one point the program uses /dev/dsp1 and as far as I know, this isn't being used in a while so an error pops as expected.

Is there any other way to get the audio input values such as easily?

Before, we could get the input just by doing "cat /dev/dsp" right? If we wanted to do something similar to that now, what should we do?

Thanks,
Levi

You can get back the '/dev/dsp' file by installing the 'oss-compat' package.

Already had it installed:


levi@laptop:~$ sudo apt-get install oss-compat

oss-compat is already the newest version.

the problem continues :S

@OP: Do you also have the package "alsa-oss" installed?

[Aqlor]

I have it too...


levi@laptop:~$ sudo apt-get install alsa-oss

Try starting your program with the prefix aoss. This fixed ut2004 for me in Ubuntu 10.10. So instead of:
ut2004
I run
aoss ut2004
The error message I get without aoss is that it can't find /dev/dsp.
