Subject: [linux-audio-dev] ALSA => OSS compatibility

Hi!

I have a default SuSE 7.1 installation which provides the alsa sound
system.

I understand that ALSA and OSS have the same programming interface, but
the device names (given as parameters to ioctl()) are different.

The following code:

  char *device = "/dev/dsp";
  if ( (audio_fd = open(device, O_WRONLY, 0)) == -1 ) {
    perror(device); //
    exit(1);
  }

produces the following output: "/dev/dsp: No such device", probably
because /dev/dsp is an OSS thing.

How do I procede to write most portable code?
Do I need the snd-pcm1-oss module?

Thanks if you can help,
Catalin
