Running roc-recv on a embedded device using ALSA

[folibis]

I have a Linux embedded device and a speaker connected to it. I can play a wav file using aplay file.wav and I can list devices using:

aplay -L
default:CARD=am3517evm
    am3517evm, 
    Default Audio Device

Bun while running roc-recv as following I get errors:
roc-recv -vv --output=CARD=am3517evm --driver=alsa
00:01:04.531 [err] roc_sndio: no backend fround: driver=alsa inout=CARD=am3517evm
00:01:04.531 [err] roc_recv: can't open output file or device: driver=alsa output=CARD=am3517evm

I've tried:

--output=CARD=am3517evm,DEV=0
--output=CARD=0,DEV=0
--output=front:CARD=am3517evm,DEV=0
--output=front:CARD=0,DEV=0
--output=default

but nothing works, the error persists

what do I wrong?

This may not be relevant anymore but directly using --driver alsa --output default:CARD=am3517evm should work

On fresh master it should be:

-o alsa://default:CARD=am3517evm

Please let me know if the issue is still relevant.
