Re: No Sound - Puzzle

I tried pavucontrol but still no sound.

I concluded there must be a conflict between also and pulseaudio so I purged pulseaudio. This did not help.

I switched the line out cable to the onboard sound card. With alsamixer set to the onboard sound card there sound and the volume can be controlled with the master/front control.

With the line out cable connected to the xonar card and the alsamixer set to the xonar card there is no sound. With pulseaudio purged there is no signal monitor but before its deletion pavucontrol showed the xonar connection and its signal monitor showed a strong signal.

Conclusion: Alsamixer shows volume settings for each sound card but does not switch to the output stream of the card, this remains the stream from the onboard  audio regardless of the alsamixer sound card selection.

There must be another setting switch the output stream.

I also wish alsa had a signal strength monitor. Maybe I should reinstall pulseaudio.
