I'm using the speaker bonnet / following instructions from adafruit: https://learn.adafruit.com/adafruit-speaker-bonnet-for-raspberry-pi/raspberry-pi-usage.
I followed all of the steps (skipping the sound tests because on a previous install I hurt my ears!) and after both reboots alsamixer still doesn't have volume controls.
If I look in aplay I can see the device:
$ aplay --list-devices
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
But amixer is totally unresponsive (amixer -h
gives the commands but amixer
and amixer scontrols
and amixer -c 0
and so on all give no output whatsover!
All of the tutorials I can find from 2 hours of searching seem to assume that if you can see a device in aplay
you should be able to see it in amixer
.
What could be wrong? Is it because I'm using Raspbian stretch? Adafruit seems to imply they don't support it: https://forums.adafruit.com/viewtopic.php?f=19&t=122904
