Acer Aspire v5 122p alsa, mpd

How to get it work

Alsa

~/.asoundrc:

pcm.dsp {  
  type plug
  slave.pcm "dmix"
}  

/etc/modprobe.d/50-alsa.conf:

options snd-hda-intel index=1  

So, HDMI is second device, and sources mixings by dmix

mpd

/etc/mpd.conf: 

music_directory         "/home/{username}/Music"  
playlist_directory      "/home/{username}/.mpd/playlists"  
db_file                 "/home/{username}/.mpd/mpd.db"  
log_file                "/home/{username}/.mpd/mpd.log"  

audio_output {  
        type                    "alsa"  
        name                    "ALSA Device"  
}  

Last steps

remove pulseaudio, if exists, and:

mkdir -p ~/.mpd/playlists  
sudo systemctl enable mpd
sudo systemctl start mpd

mpc load <playlist_name>

mpc play 1
