oss_geode - National Semiconductor Geode audio driver.

Open Sound System driver for National Semiconductor Geode/CS5530/CS5536 audio controllers.

Geode device characteristics:

  • 8/16 bit playback/record
  • mono/stereo playback/recording
  • 8KHz to 48Khz sample rate.

Some old Geode CPUs are not able to handle heavy computational loads. If your audio streams are use a lot of CPU, you can start getting garbled audio since the OSS Sample Rate Convertor is CPU intensive. Setting vmix0-src to OFF will allow you to play audio but only at a fixed rate set via vmixctl (Default: 48Khz).
