Error 'No such file or directory' when starting Squeezlite on MiniDSP SHD (Studio)

I have been running an old version of Squeezelite on my MiniDSP SHD Studio (onboard NanoPi NEO2). Recently I tried to upgrade to a later version. The latest armhf version always throws a libc6 error. The armel-static version does seem to work. However...when starting Squeezelite (either manually or as a Volumio managed service), it displays the following error message:

[16:31:43.945403] test_open:281 playback open error: No such file or directory
[16:31:43.945613] output_init_common:401 unable to open output device: default

When running Squeezelite with the -l parameter I do see the available sound cards:

Output devices:
null - Discard all samples (playback) or generate zero samples (capture)
pulse - PulseAudio Sound Server
default:CARD=I2Smaster - I2S-master, - Default Audio Device
sysdefault:CARD=I2Smaster - I2S-master, - Default Audio Device
dmix:CARD=I2Smaster,DEV=0 - I2S-master, - Direct sample mixing device
dsnoop:CARD=I2Smaster,DEV=0 - I2S-master, - Direct sample snooping device
hw:CARD=I2Smaster,DEV=0 - I2S-master, - Direct hardware device without any conversions
plughw:CARD=I2Smaster,DEV=0 - I2S-master, - Hardware device with all software conversions

But all of them (when using the -o param) give the same error. Any clues/ideas? Thanks!
