Looks like your ALSA device does not support the sample format S16_LE.

My device is:

ard 1, ID DAC', name S16 USB DAC'
Device 0, ID USB Audio', name USB Audio', 1 subdevices (1 available)
2 channels, sampling rate 44100..384000 Hz
Sample formats: S32_LE
Subdevice 0, name `subdevice #0'

and indeed does not support S16_LE.

So I assume there's no solution to this?

Many thanks for your immediate reply.

You can set the ALSA device with the --device option. Try --device=plughw:1.

Thank you very much, it works!

I am trying to find a more generic approach so that librespot uses the default alsa device. Is there any possibility to do this?

librespot does use the default device. Your default device does not support S16_LE. If you do not want to set the device with --device you have to make plughw:1 your default ALSA device. You can set this in ALSA config file. Google will help you 😄

Many thanks for everything.

I have already created an asound.conf file with the following configuration:

pcm.!default {
type hw
card 1
}

As it seems I have to search more for this.

Thank you very much for everything Joerg.

Everything is up and running buy adding the device option on the systemd.service file.

am getting this too, but with a FiiO USB DAC adding --device=plughw:1 doesn't fix it. See my report on pimusicbox through which I am using librespot pimusicbox/pimusicbox#453

The last comment was a different issue. Closing as it was solved.
