This is't a programming question see the faq: stackoverflow.com/faq – marto Jul 14 '11 at 15:12
Because you program using a certain OS doesn't mean any question regarding the OS are 'programming questions' askubuntu.com – marto Jul 14 '11 at 15:18
You have several questions which have been migrated from StackOverflow to other places, you should know this by now. – marto Jul 14 '11 at 15:31
Is there any case like it blocks from other visitors? I don't believe so – marto Jul 14 '11 at 15:39
understand why there are different sections for different types of questions. Maybe you should do more research via google. – marto Jul 14 '11 at 15:44

/dev/dsp and /dev/mixer are devices for the OSS3 sound system. The device paths are always the same on all systems.

However, due to the many limits of OSS3, most modern Linux distributions use ALSA for sound, which doesn't have dsp and mixer devices. It's possible to use OSS emulation in two ways:

  • User-mode:

    Install the alsa-oss package, then run your program through aoss:

    aoss ./sjphone

  • Kernel-mode:

    Load the snd-pcm-oss and snd-mixer-oss kernel modules, then run your program normally:

    sudo modprobe snd-pcm-oss
sudo modprobe snd-mixer-oss
./sjphone

User-mode aoss is usually the better choice.

Thank you. Its very nice answer and very confusing one of mine. I used "aoss ./sjphone", and i can use the slider of microphone only, but i cant use the speaker slider, which is disabled still. Is that has to do with aoss still or ./sjphone itself? – YumYumYum Jul 14 '11 at 22:10

/dev/dsp is the standard device in Linux for outputting or recording sound. There isn't a special device path for your soundcard or microphone.

But as you can see here it using /dev/dsp. But i do not have any mic/headphone sounds for this. What else i can apply instead of /dev/dsp in that case? e.g: i.stack.imgur.com/7WPVw.png – YumYumYum Jul 14 '11 at 17:06
