Assumpte: [DNG] Bluetooth packages for Devuan?
Hi All,
I'm trying to get a bluetooth headset working on Devuan. I'm mostly finding directions
for systemd so not sure how to do this. I seem to be missing "snd_bt*" drivers for the
kernel, as well as the "bluealsa" or "bluez-alsa" package[0], but maybe these are uneeded?

For reasons mostly unknown, both Alsa and Pulseaudio packages are installed on my system.
Originally, I just had Alsa installed and things worked well. When I installed the Steam
client app, it pulled in some Pulse dependencies and now alsa seems to control some things,
while pulse controls others.

I have some bluetooth packages installed[1] and was able to pair[2] the headset using the
bluetoothctl utility[2]. I think I have an Alsa[3] block configured in /etc/asound.conf but
it does not show up[4] with aplay -l and trying to direct aplay to the hardware address of
the paired headset does not work. Any thoughts?

- card0 are my USB speakers
- card1 is a 2.4ghz logitech headset with dying battery
- card2 and card3 are the motherboard sound jacks (I guess)
- card4 is Nvidia HDMI (I guess)
