Adafruit Speaker Bonnet issues - glancaster - 11-29-2020
I've just been setting up moOde on a Pi 3A+ with an adafruit speakerbonnet to bring an old dead radio back to life.
Initially I had a problem where starting/stopping audio (and switching stations/tracks) would cause alarmingly loud popping, and sometimes even cause the Pi to completely power off. This was solved by following adafruit's instructions (here: https://learn.adafruit.com/adafruit-speaker-bonnet-for-raspberry-pi/raspberry-pi-usage) to install a service to continuously play back silent audio.
Once this was installed, speakertest still worked (and no longer popped) but moOde always produces the following error when trying to start playback:
Failed to open "ALSA default" (alsa); Failed to open ALSA device "hw:0,0": Device or resource busy
I've determined that this can be fixed by removing the "device hw:0,0" line from the "ALSA default" audio_output section in /etc/mpd.conf and restarting MPD.
This is great, except that every time I restart the system, mpd.conf seems to get regenerated complete with the unwanted "device hw:0,0" line.
Is there a way to stop this from happening? I'm not sure if there's something in my configuration that leads to this line being added. My /etc/asound.conf is as follows:
Code:
pcm.hifiberry {
type hw card 0
}
pcm.!default {
type plug
slave.pcm "dmixer"
}
pcm.dmixer {
type dmix
ipc_key 1024
ipc_perm 0666
slave {
pcm "hifiberry"
channels 2
}
}
ctl.dmixer {
type hw
card 0
}Thanks! Really enjoying using moOde, btw. Think I am definitely going to be switching over from Volumio on my other systems

I've found a fix for this issue. A little hacky, but it works for now
In /var/www/inc/playerlib.php in updMpdConf, I've changed the following line in the section headed //ALSA local (outputs 1 - 5):
from:
Code:
"name \"ALSA default\"\n" . "device \"hw:" . $device . ",0\"\n",to:
Code:
"name \"ALSA default\"\n" . "#device \"hw:" . $device . ",0\"\n",
