The solution to my problem was that I was missingĀ  alsa-plugins-pulseaudio. It sounds like you already have that installed, so I'm not sure what your problem is.

So, I installed alsa and pulseaudio and alsa plugin then made simlink /etc/sv/alsa to /var/service and /etc/sv/pulseaudio to /var/service as well but system is not detecting any soundcard. alxamixer returns blank and nothing to configure. What went wrong?
