Ubuntu
wavesurfer package

wavesurfer cant find /dev/sound/dsp

Asked by Jont Allen

I installed wavesurfer for ubuntu, but when I try to play a sound (wav file) it gives an error message that /dev/sound/dsp
is not available, which is true. I dont see any config option to change/fix this.
Suggestions?

Use padsp to emulate the OSS /dev/dsp device:
padsp wavesurfer

Yes I did try that, but I'm not sure how exactly.
I tried to make an alias from "play" to "padsp aplay"
however that did not work. wavesurfer is a tktcl application, and I was chunking around trying to figure out
how it works. I saw several calls to "play" which I guess is a sox application. I could install sox, but that seems to not
deal with the basic issue that there is no /dev/sound/dsp device availible in ubuntu.

Since wavesurfer is looking for this device, how do I use padsp to provide that device? Do you know?

Thanks for your response in any case.

Don't do that.

You use the command:
padsp wavesurfer

Does that command not work?

I didnt understand yoru resp at first:
If I "alias" via ~/.bashrc
wavesurfer with
padsp wavesurfer
then that solves the problem.
Thank you. it seems to work just fine with that slight modification.

Problem solved.
