Hi All,

I am trying to develop an audio application on linux(ARCH = arm). I
compiled the kernel successfully as well as the rootfs. But the problem is
that I dont see /dev/dsp in my rootfs. I build the kernel and rootfs with
help of buildroot. I included udev package from buildroot but no benfit.
Any idea?


Thanks

You need to enable in kernel option OSS PCM (digital audio) API to have dsp
device.

Hi,
       I am already having that configuration in my kernel. But still I
dont have /dev/dsp node.

OK could try to enable <M> OSS Mixer API      [*] OSS Sequencer API also?
