there's no /dev/audio1 according to your dmesg and -f uses another syntax (see sndio(7) man page) > Now playing an MP3-file in VLC works, but I'm not able to adjust the volume > in VLC.

Many thanks in advance. could you do the following: build & install a new kernel with these options defined. option AUDIO_DEBUG option AZALIA_DEBUG Then, boot it, kill sndiod, and start it in a terminal with: sndiod -dd and in another terminal, play a .mp3 with mpg123 (or whatever you use) and see what errors sndiod displays and what dmesg says. Let me know if you have questions and/or you need help for the setup. thanks
