So what do we have here. Creative 5.1 channel CA0106 sound card is connected and not working.
What all could go wrong,
- your audio card itself is not detected.
- your audio driver loaded is not correct.
- pulse audio will not recognize your driver output.
- alsa mixer has problem recognizing the output
