EDIT: If it happens that you stumble across this issue and your alsa device isn't recognized, it might be due to unusual naming. White-space doesn't work inside of the configuration and has to be passed through CLI arguments for now. Example:

spotifyd --mixer "D70 "

~Sven (SirWindfield)

I'm using v0.2.11, precompiled armv6 version on a Raspberry Pi 3. My audio device is a USB DAC, the Topping DX3 Pro. Playback works as expected with the config device = plughw:CARD=Pro, but so far I've only been able to use software volume control (volume-control = softvol). But the device supports hardware volume control; I'm using it in MPD. FWIW, here is the relevant section of my /etc/mpd.conf:

audio_output {
        type            "alsa"
        name            "My ALSA Device"
        device          "hw:1,0"        # optional
        mixer_type      "hardware"      # optional
        mixer_device    "hw:1"  # optional
        mixer_control   "DX3 Pro "
}

In fact I use an MPD client's volume control to change the volume while actually listening through spotifyd. Either that or load up alsamixer in a terminal window.

Here is the output of aplay -l:

I have tried all the following "control" params in my /etc/spotifyd.conf:

#control = "Pro"
#control = "DX3 Pro"
#control = "DX3 Pro "
#control = dx3pro
#control = PCM
#control = pcm
#control = hw:1
#control = dmix:CARD=Pro,DEV=0
#control = plughw:CARD=Pro,DEV=0
#control = hw:CARD=Pro,DEV=0
#control = "DX3 Pro  Playback Volume"

All of them result in an error like this:

ALSA lib control.c:1373:(snd_ctl_open_noupdate) Invalid CTL DX3 Pro  Playback Volume
14:41:11 [ERROR] Couldn't read volume from alsa device with name "DX3 Pro  Playback Volume".

Am I using the wrong value(s) for device, mixer, and/or control?

Thanks!

I'm having the same issue on my laptop, which has an AMD HDMI audio out and built-in Realtek ALC3228 and to which I have a JDS Labs DAC connected (set as default). Both "default:CARD=DAC" and hw:0,0 result in messages such as "[ERROR] Couldn't read volume from alsa device with name "default:CARD=DAC".", "ALSA lib control.c:1373:(snd_ctl_open_noupdate) Invalid CTL hw:0,0", and "[ERROR] Couldn't set volume: Error("snd_mixer_attach", Sys(ENOENT))".

Somehow the errors have disappeared after setting:
"device = hw:DAC,0 # run aplay -L for possible values
control = hw:DAC # device for the mixer, if not the same as 'device'"
Not sure whether it was the change from "0" to DAC or setting "control" (which is commented out by default). I tried this after reading #87 BTW, don't set "volume-control" to "softvol" as someone suggests in that thread as it resulted in silence during playback for me. Only once I set it back to the default "alsa" everything fully worked. I should mention that like you I am only using ALSA (I discovered that if you install openSUSE Leap 15.1 with only a "generic desktop environment" (it really just installs IceWM with an openSUSE theme), e.g. without KDE or GNOME, pulseaudio is not installed, even though its config file is there).

@jvanwouw - could you post the output of "aplay -l" (lower-case el) and "aplay -L" on your system? Thanks!

In the past had something similar, but could also be another application.
At that time I wished at startup, or (reduce startup time) after not finding the selected audio device, the application list/logs all devices, as found by the audio library.

I'm seeing similar errors. I'm running a self-compiled binary on i386 linux, with default settings. Previously I was running v0.2.8 without any issues, but after upgrading to v0.2.20, I' seeing errors:

my config file:

device = default:CARD=Intel # Given by `aplay -L`
mixer = PCM
volume_controller = alsa
bitrate = 160
cache_path = /var/lib/spotifyd
volume_normalisation = true
normalisation_pregain = -10

Note: the errors went away when I set volume_controller=softvol, but now the music plays way softer than before.

I have same problem as OP. I have a Topping D70. I'm guessing the problem occurs from the space in the mixer control name - in my case its "D70 " (note trailing space). Quotes around the control name don't help.

Hardware audio is supported in MPD provided the mixer control name includes the space:

audio_output {
type "alsa"
name "D70"
device "hw:0,0"
mixer_type "hardware"
mixer_control "D70 "
}

Everything after the = is interpreted as the value of the field. All white-space is removed beforehand. So this is kind of intended but definitely not wanted.

What might help would be passing down the value as a program argument: spotifyd --mixer "D70 ". This should work as CLI arguments are used as is IIRC.

On fixing this issue. The "official" v1.0 release (the next release I will start working on after my finals) will include a lot of breaking changes (including moving to TOML), which will eliminate bugs like these and allows us to make a lot of name changes to the cli names to make them more stream-lined (like having all alsa specific arguments prepended with alsa. mixer for example only applies to that backend IIRC).

Many thanks, that got it working.

Good luck with the exams!
