So I decided to skip pulseaudio and only use Alsa with Dmix, and the sound works great! No problem at all with the sound. Added ”autospawn = no” to /etc/pulse/client.conf, but I notice some higher cpu usage. I have set sample rate with Alsa to 44100. mpg123 uses 30%, and mplayer 80%. With pulseaudio mpg123 it is 1-2% and mplayer 20-30%.
