Review on Adafruit Stereo Speaker Bonnet Raspberry by Bruce Willam

A great little addition to your Raspberry Pi as it not only includes digital audio but also a 3W amplifier - meaning you can hook up bookshelf speakers and go to town . This is how I configured mine to get full software volume control: in /boot/config.txt:dtoverlay=i2s-mmapdtoverlay=hifiberry-dacdtparam=spi=onin /etc/asound.conf:pcm.hifiberry { type softvol slave . pcm "plughw:0" control.name "Master" control.card 0}pcm.!default { type plug slave.pcm "softvol"}pcm.softvol { slave { pcm "sysdefault" } control { name "softvol" card 0 }in /home/pi/.asoundrc:pcm.!default { type plug slave.pcm "softvol"}pcm. softvol { slave { pcm "sysdefault" } control { name "softvol" card 0 }} Boot with your hood, then make sure your Raspbian system (Menu->Settings-> audio device) shows "snd_rpi_hiberry_dac (alsa mixer) (default)" selected - make it the default By default (see image), if you use VLC you need to set the sound device to DAC; If you're using the Audacious player, go to Settings, then click Audio, then click the ALSA Output Settings button. Select the configuration shown (see figure). I basically set up a few miniature internet radio stations at home and simultaneously stream music around the house (Audacious and VLC play .xspf files). Sound to your Raspberry Pi - and it offers software control! (I control all my RPs via VNC sessions and run them headless) this is a five star product!
